The intensity ratio of TO and LO inMCT was observed to be different. Such difference was explained in terms of the different Ramangeometry arrangement.〓. The laser-induced micro-photoluminescence in the range of 1000～5000〓(1.34eV～1.83eV) was found for the first time in LPE MCT epilayer. The center of photoluminescence wasat 2750〓 or 1.62eV and the FWHM of luminescence was 2000〓 or 0.25eV. We assume thatthe photoluminescence is due to recombination of electron from an anion vacancy resonance levelto the top of valance. In addition, new Raman shift was observed at 750〓 in LPE MCTepitaxial film.〓. The laser-induced micro-photoluminescence with quasi-periodic structure was observed forthe first time at room temperature in one of MOVPE MCT epitaxial film samples. The range offluorescence was from 1.46eV to 2.21eV, i.e., 1.73eV above the conduction band edge.
