Photoluminescence studies of ZnSe starting materials and vapor grown bulk crystals

摘要

Low-temperature photoluinescence (PL) spectra were measured on ZnSe starting materials provided by various vandors and on bulk crystals grown from these starting materials by physical vapor transport (PVT) to study the effects of purification and contamination during PVT process. The impurity levels in one set of starting material/grown crystal were also measured by glow discharge mass spectroscopy (GDMS).
