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。

The experimental result shows that the main determinative factor is the temperature of the sea water for the growth after the transplantation; the optimal temperature for the growth of Zostera marina L. is 10~20℃; it is strongly salt-tolerant and it can grow at the salinity range of 20‰~48‰ normally; its rhizome is the optimal organ for culturing and the optimal hormone concentration for the calluses induction is 2mg/L or so.

The growth mechanism of silver seed on silicon has been presented: at first, the silver monolayer and multilayer firstly grows onto silicon without fully covering the surface at the expense of silicon etching due to the silver seed attracting the electron from silicon, after that, the monolayer coalesces together, forming continuous grain film with some silver atoms diffusing into the silicon and the multilayer still grows thick simultaneously.
