Abstract

Rubidium sulfate crystal is an inorganic material and it is doped with an organic material viz. L-leucine to improve the various properties of the host crystal. L-leucine doped rubidium sulfate (LLRS) crystals have been grown by solution method. LLRS crystals have been harvested after the growth period of 30 days. The grown LLRS crystal is observed to be crystallizing in orthorhombic structure by single crystal XRD studies. Mechanical studies were carried out to find the mechanical strength and other parameters. Dielectric studies of L-leucine doped rubidium sulfate crystals were carried out to evaluate dielectric constant, dielectric loss and activation energy. UV-visible-NIR spectral studies were done in the wavelength range 200-1100 nm and linear optical properties like transmittance, absorption coefficient and extinction coefficient of samples have been evaluated. Second order Non Linear Optical (NLO) studies of the grown crystal of LLRS were carried out by Kurtz-Perry technique. The fundamental absorption was noted at 280 nm and at 278 nm for undoped and L-leucine doped rubidium sulphate crystals respectively. The optical band gap of LLRS crystal was found to be slightly more than that of undoped rubidium sulphate crystal. The SHG efficiency of LLRS crystal is observed to be 0.61 times that of the reference KDP sample.
