The single crystals of 2 wt% ADP doped K2SO4 crystal was synthesized and white coloured good optical quality single crystals were grown deionized water as solvent by slow evaporation solution growth technique at room temperature. From the single crystal XRD, the doped K2SO4 crystal belongs to orthorhombic system. From the powder XRD, appearance of sharp and well defined Bragg's peaks confirmed the crystalline nature of the grown crystal. T The doped K2SO4 crystal is active in the UV-Vis region and it has good transparency of about 70% with lower cut-off wavelength 390 nm. The band gap of the…mehr

Produktbeschreibung
The single crystals of 2 wt% ADP doped K2SO4 crystal was synthesized and white coloured good optical quality single crystals were grown deionized water as solvent by slow evaporation solution growth technique at room temperature. From the single crystal XRD, the doped K2SO4 crystal belongs to orthorhombic system. From the powder XRD, appearance of sharp and well defined Bragg's peaks confirmed the crystalline nature of the grown crystal. T The doped K2SO4 crystal is active in the UV-Vis region and it has good transparency of about 70% with lower cut-off wavelength 390 nm. The band gap of the crystal is found to be 4.6 eV and the estimated refractive index is found to be 1.37 at 532 nm. From the microhardness, the hardness value found is to be n = 3.1, that the crystal belongs to soft material category.. The SHG efficiency of doped K2SO4 is 0.457 times greater than that of KDP. It is found that the conversion efficiency of the doped crystal is greater than pure K2SO4.
