STRUCTURAL, OPTICAL AND ANTIBACTERIAL STUDIES OF PURE & AMINO ACID ADDED SINGLE CRYSTALS

Abstract

Alkali, Alkaline earth and transition metal ions doped L-proline single crystals were grown by solution growth technique. Due to variation in the nature of dopant, there is a modification in the growth habit, nonlinear optical property and mechanical hardness of the doped crystals. Fourier transform infrared (FTIR) spectra reveal strong absorption bands occur due to the presence of L-proline. UV–visible spectra show an improvement in the optical transmittance while doping on L- proline. The unit cell parameters and cell volume are obtained by powder X-ray diffractometer. Effect of dopant on the crystal defect on the grown crystals was characterized by Optical Microscopy. Anti-microbial study of the grown crystals was analyzed using gram positive and gram-negative microorganisms.
