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 swallowed or comes in contact with the eyes and skin it is necessary to seek medical attention. Current research is mostly focused on controlling 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 irritates. 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. Emergency response personnel are advised to wear positive-pressure breathing apparatuses and normal work clothes. If there is a small amount of leakage, use a clean, dry shovel to collect it in a container that has been covered. Large amounts of leakage: collect and dispose at waste disposal sites.
2. Protective measures
Respiratory System Protection:
You must wear a dust-proof electric filter-air-supply respirator if you might be exposed to the dust. When performing an emergency rescue or evacuation, it is recommended that you wear a dust-proof 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 normal saline. Seek medical attention.
Quickly leave the area and go somewhere with fresh air. Airways should be kept clear. Oxygen is recommended if breathing becomes difficult. Give artificial respiration as soon as breathing stops. 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 ground
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.
