Inhomogeneity study of alanine and valine-doped TGS crystal using micro-probe Raman spectroscopy
Micro-probe Raman spectroscopy is used for studying positional inhomogeneity in alanine-doped TGS crystals. 20 data points are measured along the c- and a-axes in b-plane. Several known Raman peaks are observed unchanged, but most other peaks are found to be changed remarkably. The major difference in spectra are found to be related to SO/sub 4/ vibrations. The vibrational frequencies are found to be lowered near the seed position. The most unstable spectra are detected in the vicinity of the seed region.
