Effect of TGS on crystal growth and properties of ammonium dihydrogen phosphate (ADP)

Abstract

Ammonium dihydrogen phosphate (ADP) is an excellent inorganic nonlinear optical material having scalenohedral class of tetragonal structure provides order disorder phase tansitions used in various instrumental applications. Good quality of pure and three different wt% of TGS doped ADP single crystals have been grown by natural evaporation method at room temperature. The structural, optical and dielectric characterization of as-grown pure and doped ADP crystals was made using powder XRD, UV–Vis and dielectric spectroscopy. Band gap energies of the pure and doped crystals have been calculated at cut off frequencies using the UV–Vis spectrum analysis. Dielectric constant and dielectric loss of the grown crystals is measures using VNA with frequency ranges 200 MHz to 20 GHz at room temperature.
