A comparative analysis of chromium doped l-alanine cadmium chloride monohydrate single crystal using X-ray diffraction, thermal and optical techniques for nonlinear optical applications

Single crystals of 1 and 3 mol% Cr3+ doped l-alanine cadmium chloride monohydrate were grown by slow evaporation solution technique using double distilled water as solvent. The amount of chromium incorporated into crystal lattice was found using atomic absorption spectroscopy and was found that actual concentration incorporated into lattice was few ppm only. Lattice dimensions of grown crystals were analysed using powder X-ray diffraction technique and found that the crystals crystallised in monoclinic system with space group C2. Crystalline perfection of grown crystals were assessed using High Resolution X-ray diffraction and X-ray topographic technique and was found that incorporation of chromium has significantly improved the crystalline perfection. Thermal stability of doped crystals were studied using thermogravimetric analysis and found that thermal stability was improved with the incorporation of chromium. Further there optical properties were analysed using UV–vis spectroscopy.
