采用硫化助熔剂法制备了CaS∶Sm~(3+)荧光材料。它具有好的结晶性能,颗粒表面光滑且不结团;有较好的抗水解能力。在阴极射线激发下,其色坐标值为:x=0.563;y=0.423。Sm~(3+)离子的最佳浓度是3×10~(-4)mol,能量效率约为12％。可作为新型琥珀色终端显示器用荧光材料。在CaS基质吸收边的低能量方向观察到一个吸收带,认为它可能是电子从S~(2-)到Sm~(3+)的电荷转移带。 The CaS:Sm ~ (3+) fluorescent material was prepared by sulfidation flux method. It has good crystallization properties, the particle surface is smooth and not clumpy; have good resistance to hydrolysis. Under the excitation of cathode ray, its color coordinate value is: x = 0.563; y = 0.423. The optimum concentration of Sm ~ (3+) ion is 3 × 10 ~ (-4) mol and the energy efficiency is about 12%. Can be used as a new fluorescent amber terminal display. An absorption band is observed in the low energy side of the CaS absorption side of the CaS matrix, suggesting that it may be a charge transfer band for electrons from S 2 - to Sm 3+.
