There is a typical antagonism between selenium and metals, and selenium with different valences can combine with metal ions to form metal selenides. Metal selenides have attracted much attention in recent years due to their excellent optoelectronic and catalytic properties, and have potential applications in solar cells, pollutant degradation, and photocatalysis. Application of Selenide Powders Lead selenide is regarded as a new type of semiconductor material due to its large exciton Bohr radius and high optical sensitivity. Cadmium selenide is a typical fluorescent quantum dot, which is widely used in the preparation of light-sensitized solar cells and biomedical imaging. Bismuth selenide is used as a carrier for anticancer drugs due to its high photothermal conversion efficiency and low toxicity in the human body.

Is boron amorphous or crystalline?

Boron may be prepared as a crystalline or amorphous form. A-rhombohedral a (a-R), and b–tetragonal b (b–T) are the most well-known types of crystallization. Sometimes, it is possible to synthesize boron in the forms of a–tetragonal and g–orthotropic (g), allotropes. It is possible to also find two amorphous forms: one that is finely powdered and …
