前言ZnS:Mn 交流薄膜电致发光器件,在直流电压激发下也得到了发光,但经多次老化测量发现,在直流激发下,亮度衰减较快.在单极性脉冲电压下激发,老化也较快.实验证明,对称正弦交流电压是较好的激发方式,经几百小时老化,没发现亮度有大的衰减.我们认为在实际应用中,尽量采用正弦
Preface ZnS: Mn AC thin-film electroluminescent device, under the DC voltage excitation also got the light, but after several aging measurements found that under the DC excitation, the brightness decay faster in unipolar pulse voltage excitation, aging Faster.Experiments show that the symmetrical sinusoidal AC voltage is a better excitation method, after hundreds of hours of aging, did not find the brightness of a large attenuation.We think in practice, as far as possible the use of sine
