The extensive study of solubility, nucleation kinetics, surface analysis, thermal studies, dielectric properties, photoelastic, crystalline, photoluminescence behaviour of itaconic acid doped ammonium dihydrogen phosphate single crystals for nonlinea

Abstract Pure ADP single crystals and ADP crystals doped with 1, 3, and 5 mol% itaconic acid (ITA) were synthesized by slow evaporation of an aqueous solution. The dielectric analysis indicated that doped ADP crystals exhibited reduced dielectric loss and enhanced dielectric constants compared to their pure crystal. Etching studies show that the crystals have a high level of perfection. ITA doping facilitates crystal growth, nucleation, and induction. The laser damage threshold of a SEST grown ITA doped ADP crystal has been examined. Solubility and metastable zone width were measured in pure ADP and ITA doped ADP samples. The effect of 1, 3, and 5 mol% itaconic acid (ITA) doping on the thermal properties of ADP single crystals grown by slow evaporation was studied. The primary emission color was determined from photoluminescence spectra, which showed an emission band at 531 nm. The Sellmeier dispersion relation and the Wemple-DiDomenico single oscillator model were used to analyze optical dispersion. The photoelastic behavior of the pure ADP and ITA doped ADP crystals was investigated, with ITA employed as a variable birefringent compensator. HRXRD analysis indicated improved crystalline quality in the pure ADP and ITA doped ADP crystal.
