Alloy Disordering Effects on the Thermal Conductivity and Energy Gap Temperature Dependence of CdZnSe Ternary Crystals Grown by the Bridgman Method.

Investigated in this work, CdZnSe-mixed ternary compounds were grown by the Bridgman method. Several compounds with zinc content varying in the range 0 < x < 1 were produced between two binary parents, CdSe and ZnSe crystals. Using the SEM/EDS technique, the accurate composition of formed crystals was determined along the growth axis.

Generation of red light with intense photoluminescence assisted by Forster resonance energy transfer from Znq and DCM thin films.

In this work, a novel experimental investigation of photoluminescence properties of Znq thin films co-doped with different concentrations of DCM were performed. The thin films were successfully deposited on glass substrates with different compositions, under high vacuum, by using the vacuum evaporation technique. For all compositions, the photoluminescence was measured at room temperature and also at low temperature in a wide range from 77 to 300 K with a step of 25 K in a high vacuum.
