STUDIES ON GROWTH, MORPHOLOGY, SPECTRAL AND MECHANICAL PROPERTIES OF SOME DOPED L-ALANINE FAMILY OF SINGLE CRYSTALS

K. Seethalakshmi, S. Perumal, P. Selvarajan.

Abstract
Single crystals of L-alanine (LA), L-alanine doped with potassium chloride (LAPC) and L- alanine doped with potassium bromide (LAPB) have been grown from solution by slow evaporation technique at ambient temperature. The effects of dopants in the host L-alanine crystals have been investigated from growth, morphology, spectral and mechanical properties. Scanning Electron Microscopic (SEM) analysis was used to compare morphology of the grown crystals. The functional groups of the samples were identified by FTIR spectral analysis. The hardness of the crystals was found out by Vickers microhardness tester.

Key words: Characterization, Slow Evaporation, Single Crystal, SEM analysis, Vickers microhardness test.
