Abstract
Current investigation explores the impact of Nd3+ ion on linear and nonlinear optical properties of ammonium zinc sulphate hydrate (AZSH) crystal for defining its suitability for photonic device applications. The Nd3+ ion influenced AZSH (Nd-AZSH) crystal has been grown by conventional slow solvent evaporation technique at room temperature. The energy dispersive spectroscopic (EDS) technique has been utilized to uncover the chemical constituents of the Nd-AZSH crystal. The powder X-ray diffraction technique has been employed to evaluate the structural parameters of Nd-AZSH crystal. The influence of Nd3+ on linear optical transmittance of AZSH crystal has been examined within the wavelength range of 200–1100 nm by means of UV–vis spectral analysis. The attributes of Nd3+ in promoting the second harmonic generation (SHG) efficiency of AZSH crystal has been explored by means of Kurtz-Perry powder test. The Nd-AZSH crystal has been tested by the He-Ne laser assisted Z-scan technique to investigate the third order nonlinear optical (TONLO) characteristics at wavelength 632.8 nm. The TONLO refractive index (n2), absorption coefficient (β) and susceptibility (χ3) has been evaluated using the Z-scan data.
