【 摘 要 】

Single crystals of Zn_{1â€�?�ð�?��?}Mn_ð‘�?Te were prepared by vertical Bridgman crystal growth method for different concentrations of Mn. Chemical analysis and reflectivity studies were carried out for compositional and band structure properties. Microscopic variation in composition between starting and end compounds was observed from EDAX analysis. Linear dependence of fundamental absorption edge (𝐸₀) as a function of Mn concentration (ð‘�?) was expressed in terms of a straight line fit and a shift in 𝐸₀ towards higher energy was observed in reflectivity spectra of Zn_{1â€�?�ð�?��?}Mn_ð‘�?Te.
