; Abstract: The observation of efficient blue, green, orange and red luminescence from CdS nanocrystals made by using a reverse micelle method was reported. The blue luminescence about 480 nm is attributed to the radiative recombination of electron-hole pairs. The red luminescence around 650 nm is due......

Low Temperature Luminescence Properties of Tm3+ Doped Aluminate Phosphor Zhuang Weidong1,Huang Xiaowei1,Xia Tian1,Teng Xiaoming1,Zhao Chunlei1,Cui Xiangzhong1 (1.National Engineering Research... and UV emission spectra at 20, 50 and 100 K show that the low temperature luminescence intensities become weak gradually with the increasing of the temperature under 147 and 254 nm excitation......
Upconversion Luminescence of YLiF4 :Er3+ Synthesized by Hydrothermal Method Pei Xiaojiang1,Hou Yanbing1,Zhao Suling1,Xu Zheng1 (1.Institute of Optoelectronic Technology, Beijing Jiaotong University... absorption is the main mechanism of upconversion emission. When Er3 + content is larger than 1.5 %, both of the excite-state absorption and energy transfer lead to the upconversion luminescence......
and 514.5 nm lasers are used as excitation sources. The luminescence of fergusonites results mainly from Er3+, whereas that of brocenites is produced by Er3+ and Eu3+. The absorption spectra indicate that Nd3+ may be an important sensitizer to the luminescence of Er3+ and Eu3+.

The luminescence spectra show that the LB films have the fine luminescence properties, and the LB films emit strong luminescence under......
of lanthanide luminescence with emphasis on f-f transitions, the sensitization mechanisms, and the assessment of the luminescence efficiency of lanthanide-containing emissive molecular edifices. Emphasis was then put on two fast developing aspects of lanthanide luminescence: materials for telecommunications and light emitting diodes, and biomedical imaging and sensing. Recent advances in NIR-emitting......
