Growth and evaluation of linear optical, nonlinear optical, mechanical and thermal properties of a novel bio-organic chlorophyll-b of Ficus religiosa added ammonium dihydrogen phosphate optical single crystal

Abstract

Over the past few years, organics doped nonlinear optical materials have earned tremendous attention owing to their effective applications in Opto-electronics and Photonics device fabrications. In this pursuit, chlorophyll-b doped ADP (CHLBADP) optical single crystals are grown by a slow evaporation technique at ambient temperature. The single crystal X-ray diffractometer analysis proclaims that the grown CHLBADP crystal has a tetragonal symmetry with the lattice parameters a = b = 7.54˚A, and c = 7.57˚A. Optical band gap and the lower cutoff wavelength of the CHLBADP crystal are found to be 261 nm and 6.3 eV respectively. Optical parameter analysis confirmed that CHLBADP crystal is well suited for optical applications. The weight and atomic percentage of the CHLBADP crystal is confirmed by using energy dispersive analysis spectrum (EDAX). The Photoluminescence spectrum of the CHLBADP crystal shows the blue and red emission at 475 and 658 nm respectively. The SHG efficiency of CHLBADP is 1.44 times greater than that of KDP. Microhardness studies of CHLBADP are carried out using a Vicker’s hardness analyzer, hardness parameters of CHLBADP crystal plays a key role when they are designed for optical device applications. The organic material (Chl-b) doped ADP it may be applied to the power grid, electronics lenses, sensors and Photonics.
