Growth, thermal and third order nonlinear optical properties of bisglycine strontium bromide trihydrate single crystal

Bisglycine strontium bromide trihydrate (BGSBT) single crystals have been grown by way of slow evaporation. Crystallization of BGSBT in the orthorhombic system has been revealed in XRD analysis, and functional groups established through FT-IR and FT-Raman analyses. Optical transparency of BGSBT in the 300 to 1100 nm range has been manifested through UV-Vis NIR spectral analysis. BGSBT is seen to come under the soft materials category, as understood from Vickers microhardness study. Change in dielectric constant and dielectric loss as frequency varies is monitored at different temperatures. Thermal stability of BGSBT until 104 degrees C is verified from TG-DTA analysis. The presence of Sr and Br has been established from Energy Dispersive X-ray analysis. The nonlinear optical properties have been determined with Z-scan method. The emission of violet light is a property revealed by the photoluminescence spectrum of BGSBT. Structural perfection and growth character of BGSBT crystal is implicit from etching studies.
