A new kind of multi-layer structure has been used to prepare the SrS:Ce3+ thin film ACEL devices. The different between this device and conventional ZnS device is that there is a thin layer of pure ZnS,as a barrier layer, sandwiched between the Y2O3 dielectric layer and the SrS:Ce3+ active layer. The SrS phosphor layer was deposited by electron beam evaporation at higher substrate temperature of 350℃.X-ray diffraction analysis indicates that a high degree of crystalline perfection was formed at this temperature. The saturated luminescence brightness observed for SrS:CeCl3 TFEL devices was about 100cd/m2 under 5kHz AC excitation.The B-V and η-V characteristics of the SrS:Ce3+ ACEL decive are similar to the ZnS device. The spectrum of SrS:Ce3+ ACEL thin film consists of many peaks. Comparing the EL spectra of SrS:Ce3+ with the reported CL spectra of SrS:Ce3+ phosphor, it is evident that the two main emission bands having peaks around 490nm and 540nm are due to parity allowed transition of 2D(5d)-2F5/2(4f) and 2D(5d)-2F7/2(4f). To deter- mine the angle dependence of the device, the spectra of different emission angles with normal were measured. The intensities of the peaks change obviously with the angles, but peak positions change a little and there is no change in the number of peaks, these suggest that many dfferent kinds of luminescent centres may have been formed in SrS:Ce3+ ACEL thin film devices.Compare the luminescent properties of SrS:CeCl3 thin film with SrS:CeF3 thin film,we observed that CeCl3 is more efficient than CeF3,but the spectral bands of latter are apparently broader than the bands of former, the reason for this may be that there are some Cl atom escaped from the SrS film at the high temperature of 350℃. It has also been observe that the efficiency of SrS:Ce3+ thin film is higher than the efficiency of ZnS:Ce3+ . The exact mechanism is not clear, but it is likely that SrS provides a suitable surroudings for the excitation of Ce3+ ion.

本文采用了SnO_2/Y_2O_3/ZnS/SrS:Ce~(3+)/ZnS/Y_2O_3/Al这种多层结构制备了SrS:Ce~(3+)薄膜器件,并得到了较亮的蓝色交流电致发光。在5KHz正弦交流电压的激发下,该器件的最大亮度为100cd/m~2左右。讨论了衬底温度与薄膜结晶完整性的关系,认为衬底温度在300—400℃之间有利于获得良好的结晶状态。本文还对SrS:Ce~(3+)薄膜的光谱特性进行了讨论,比较了CeF_3和CeCl_3分别掺杂时,SrS薄膜的发光特性‘发现CeCl_3掺杂较CeF_3掺杂好。同时还看到,SrS:Ce~(3+)薄膜的ACEL亮度和效率较ZnS:Ce~(3+)薄膜要高,认为可能的原因是SrS基质提供了一种适合Ce~(3+)激发的环境。
