Photoluminescence and Band gap energy of Ca-Sr Tartrate

摘要

Mixed Crystals of Calcium-strontium tartrate were grown by a gel technique using single diffusion method. The effect of various parameters like pH of gel, gel density, gel aging, and concentrations of reactants etc. on the growth of these crystals was studied. Faint yellowish, semi-transparent, whitish, rhombohedra shaped maximum size 3 mm × 5 mm, thickness 2mm crystals were obtained. The crystals grown were characterized by SEM, UV, and PL. The results of these observations are described and discussed.
