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.
Protection has been used for respiratory protection.
Wear protective clothing and protective tape.
wear rubber gloves.
The workplace is a no-smoking zone. Attention to personal hygiene.
3. First aid measures
Rinse the skin well with soap and hot water. Seek medical attention
Lift the eyelids and rinse them with water running or a normal saline solution. Seek medical attention.
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.
Get medical help if you vomit and drink enough warm water.
Fire fighting method:
Special protective clothing is required for firefighters.
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.
