Structural, linear and non linear optical, electrical, piezoelectric and thermal investigation on new semi-organic single crystal for microelectronics and high power laser applications: A brucinium di-hydrogen borate hydrate

The fine quality of brucinium di-hydrogen borate hydrate (BDHBH) single crystal was harvested from the saturation solution by slow evaporation technique. Crystal structure was solved by SHELEX program and which confirms that the title crystal belongs to monoclinic crystal system with non-centro symmetric space group P21. Linear optical parameters such as transparency range, cut-off wavelength, optical band gap, electro-negativity and refractive index of the title crystal were computed by UV–Visible study. The high surface laser threshold damage (SLDT) value shows its suitability in laser application coupled with high power output. Second order non-linear behavior was confirmed by Kurtz-Perry powder technique. The lesser value of FWHM shows the better quality of the grown crystal. Title compound is a utensil candidate for blue emission applications in field of optical device fabrications which is demonstrated by fluorescence optical study. The grown crystal exhibits RISE which is analyzed by Viker's micro hardness measurements. Dielectric study shows, the dielectric constant decreases exponentially by increasing frequency which confirms the normal dielectric performance and low dielectric loss indicates that, the lower concentration of defects in the title compound. Piezoelectric charge coefficient and piezo-voltage of BDHBH crystal were found to be 2 p C/N and 0.0175 p V m N−1 respectively. The multiple decomposition stages of the title compound were discussed in detail by various thermal analyses such as TGA, DTA and DSC.
