中文百科

碲化锌

STM images of the ZnTe(110) surface, taken at different resolutions and sample rotation, together with its atomic model.[3]

碲化锌是一种无机化合物,化学式为ZnTe。它是一种半导体材料,能隙2.23–2.25eV。

碲化锌的制备方法和硒化锌类似,有干法和湿法两种。干法是将单质碲和锌在氢气气氛中加热(如果在空气中反应,则会氧化),产物升华,得到红棕色的碲化锌:

Zn + Te → ZnTe

湿法是用碲化钠和乙酸锌在水溶液中反应,产物是黄棕色的水合物沉淀:

Na2Te + Zn(CH3COO)2 → 2 CH3COONa + ZnTe(水合)↓
