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.

2首次在LPE生长的碲镉汞外延薄膜的显微Raman谱中，在1000～5000〓范围发现了激光激发显微荧光，该荧光的发光范围换算为电子伏特标度为1.34eV～1.83eV，荧光的发光中心大约位于2750〓，即1.62eV，发光的半峰高宽约为2000〓或0.25eV；指出该显微荧光来源于碲镉汞薄膜中的阴性离子空位共振能级的激光激发发光；观察到了碲镉汞外延薄膜中一个新的Raman散射峰，位于750〓位置； 3首次在一块用MOVPE方法生长的〓Te外延薄膜的显微Raman谱中，发现了1.46eV至2.21eV范围并伴随有周期结构的显微荧光峰，该发光峰对应的能带中心位于〓Te材料导带底上方1.73eV，通过研究得出样品在1.46eV至2.21eV范围的显微荧光峰是由于改进 MOCVD 生长工艺，提高了碲镉汞外延薄膜的结构质量所致；通过分析指出该显微荧光来源于外延层中的阴性离子空位的共振能级发光。

Using different dosages of He-Ne laser irradiated the developmental eggs of Antheraea yamamai. Compared with control plot, their hatchabilities were increased and their larval duration was influenced. Individual such as abnormal and premature mutants was also obtained. The blood protein and esterase isoenzyme of their pupa were analyzed with PAGE, found some changes in band r umber and activity. All those indicated that He-Ne laser has some inductive effects on physiological and biochemical characters of Antheraeayamamai.
