| 摘 要： | 纳米材料特异性能的开发与利用,是当今纳米材料科学研究中的热点之一.国外新近报道了1～3]TiO2纳米晶粒在光学增益体系中的一种新应用.据报道,将TiO2纳米晶粒散布到染料罗丹明过氯酸盐的甲醇溶液中,在Nd:YAG 532 nm激光激发下,产生出奇特的光学现象:发射光纯度极高,波长宽度为2～3 nm,发射峰幅度成10倍地放大,激发能量有明确的阈值,且为各向同性发射.

| Abstract: | The effects of temperature and pressure on the preparation of Al 2O 3 coated TiO 2 nanocrystals as well as its antiflocculation were investigated in this paper. The experimental result reveals that the coating process has greatly improved the antiflocculation of TiO 2 nanocrystals in the solvent of ethanol, however, temperature and pressure have little different effect on it. |
