Sun Jiaming, Zhong Guozhu, Fan Xiwu, Zheng Chenwei. STUDY OF THE ELECTROLUMINESCENCE AND EXCITATION PROCESS OF CaS:TmF<sub>3</sub> FILM PREPARED BY RADIO FREQUENCY MAGNETRON SPUTTERING[J]. Chinese Journal of Luminescence, 1998,19(1): 31-35DOI:
Blue electroluminescence was reported for the first time from CaS:TmF
3
thin film prepared by radio frequency magnetron sputtering method.Brightness-applied voltage characteristic was investigated in alternating current thin-film electroluminescent device.The integrated intensity ratio of infrared to blue peak of electroluminescent spectra was compared with that of the photoluminescent spectra from CaS:TmF
3
powder excited by different photon energy.The main excitation processes in CaS:TmF
3
electroluminescent thin film was considered to be energy transfer from the host to Tm
