本文报道用物理蒸气输运(PVT)法,通过对原料的提纯和控制组分蒸气压生长出高纯CdS单晶.叙述了控制晶体化学比的方法并通过比较CdS的激子光谱以评价材料的纯度.
In this paper, we report the method of controlling the chemical ratio of crystals by means of the physical vapor transport (PVT) method and the growth of high purity CdS single crystals by the purification of the raw materials and the control of the vapor pressure of the components. By comparing the exciton spectra of CdS, Purity.
