The expeximental results of infrared spectra and DSC technique show that when the concentration of Te precipitates/inclusions( w Te ) is higher than 0.6wt%, the IR transmittance is lower than 55% and then quickly decreases as w Te increase.

• CdZnTe晶体的红外透射光谱和差示扫描量热法结果表明，当晶体中Te沉淀相含量（wTe）大于0.；6wt%25时，其红外透射比低于55%25，并随wTe值的增大而下降；
