How can infrared remote control quantum technology

What color is cadmium selenide? It is a crystal that can be gray-brown, red or even orange. Cadmium Selenide is the solid binary compound made of cadmium (Cd) and selenium. It is an infrared transparent n-type material. The particle size provided by Materials: particles, 100 mesh; purity: 99.9%.
Is cadmium selenide poisonous?
Selenium is toxic and can cause a great deal of toxicity. Cadmium selenide has been proven to be a carcinogen for humans. If cadmium is swallowed or comes in contact with the eyes or skin, it must be treated by a medical professional. Current research is primarily focused on the control of development.

Uses for cadmium selenide
1. Optoelectronic devices
2. Laser diode
3. Biomedical imaging
4. Nano sensing
5. High-efficiency solar cells
6. Thin film transistor

How to store cadmium selenide?
Store in an airy, dry, and cool warehouse. Keep away from heat and flame sources. The package is sealed. Store the chemical separately from other oxidants, acids and edible chemicals. Equip yourself with enough fire equipment. It is important to equip the storage area with appropriate materials for containing leakage.

Can cadmium be harmful to your health?
The body is harmed by inhalation and oral administration. It is irritating. Contact can cause nausea, headaches and vomiting. Chronic effects: kidney and lung damage. Heat or acid can create highly toxic hydrogen-selenide gas. Selenium oxide is produced by combustion (decomposition).

Emergency treatment methods
1. Leakage emergency treatment
Restrict access and isolate the contaminated area. It is recommended emergency response personnel use self-contained positive pressurized breathing apparatus, and wear general work clothing. If there is a small amount of leaking, use a clean, dry shovel to collect it in a container that's covered and kept clean. Large amounts of leakage: collect and dispose at waste disposal sites.
2. Protective measures
Respiratory System Protection: You must wear a hood type electric air-supply dust-proof filter respirator if you might be exposed to the dust. During an emergency evacuation or rescue, it is advisable to wear a respirator.
Eye protection Protection has been used for respiratory protection.
Body protection Wear protective clothing and protective tape.
Hand protection wear rubber gloves.
Others: The workplace is a no-smoking zone. Attention to personal hygiene.
3. First aid measures
Skin contact Rinse the skin well with soap and hot water. Seek medical attention
Eye contact Lift the eyelids and rinse them with water running or a normal saline solution. Seek medical attention.
Inhalation: Quickly leave the scene and go somewhere with fresh air. Airways should be kept clear. Oxygen is recommended if breathing becomes difficult. If breathing stops, you should immediately start artificial respiration. Seek medical attention.
Ingestion: Get medical help if you vomit and drink enough warm water.
Fire fighting method: Special protective clothing is required for firefighters.
Extinguishing agent Carbon dioxide dry powder, sandy soil

Remote control quantum technology using infrared
Los Alamos' team developed a high-efficiency infrared LED that is tuned to specific wavelengths. This was achieved by adding an intermediate layer made of mercury sulfide between the core and shell interface.

Selenide Powder

Cadmium Selenide CdSe Powder CAS 1306-24-7

About Cadmium Selenide CdSe Powder :
Cadmium selenide is an inorganic compound with the molecular formula CdSe.What is the name of CdSe? Cadmium selenide. It is a black to red-black solid and is classified as an N-type semiconductor II-VI.So far, research on the salt has focused on its nanoparticles. Cadmium selenide (CdSe) is a hexagonal modified tetrahedral semiconductor with a wurtzite structure.CdSe is a uniaxial optical semiconductor with two dielectric functions. The measurement of the reflectivity spectra of CdSe crystals under the action of polarized light shows that the electric vectors parallel to and perpendicular to the hexagonal axis are quite different.
Cadmium selenide is a solid binary compound of cadmium and selenium. It is an n-type semiconductor material that is transparent to infrared light. However, p-type doping of cadmium selenide occurs in the use of nitrogen. Wurtzite, sphalerite and rock salt are the three known forms of cadmium selenide crystals. Cadmium is a toxic heavy metal, and selenium can be toxic in large amounts. Cadmium selenide is therefore a known carcinogen in humans and requires medical attention if swallowed or if it comes into contact with the eyes and skin. Most of the current research work focuses on development control.
What is Cadmium Selenide structure? CdSe comes in three crystalline forms: hexagonal wurtzite (hexagonal), galena (cubic), and halite (cubic). The CdSe structure of sphalerite is unstable and converts to wurtzite after moderate heating. The transition starts at around 130 ° C and can be completed in a day at 700 ° C.Halite structures are only observed at high pressures.

How is Cadmium Selenide CdSe Powder produced?
Cadmium selenide (cadmium selenide synthesis) is produced in two different ways. Bulk crystalline CdSe was prepared by high-pressure vertical Bridgman method or high-pressure vertical zone melting method
CdSe can also be produced in the form of nanoparticles. There are several methods for preparing CdSe nanoparticles: retention precipitation in solution, synthesis of structural media, pyrolysis at high temperature, ultrasonochemistry, and radiolysis
Under controlled conditions, alkyl cadmium and tri octyl phosphine selenide (TOPSE) precursors were introduced into a heated solvent, and cadmium selenide was prepared by retention precipitation in a solution
ME2Cd + TOPSE →CdSe +(by-product)
High-temperature pyrolytic synthesis is usually carried out using aerosols containing volatile mixtures of cadmium and selenium precursors. The precursor aerosol is then brought into a furnace containing inert gases such as hydrogen, nitrogen or argon. The precursor reacts in the furnace to form CdSe and several by-products.
 
Applications of Cadmium Selenide CdSe Powder:
CdSe materials are transparent to infrared (IR) light and have limited applications in photoresistors and Windows of instruments that utilize infrared light. The material also has high luminescent properties.CdSe is a component of the pigment cadmium orange.
