ZHU Ning, MENG Xian-yu, SHI Pan. Discussion on the Deterioration Mechanism of Different Electroluminescent Phosphors[J]. Chinese Journal of Luminescence, 2000,21(2): 159-161DOI:
In the discussion the deterioration mechanism of difference electroluminescent phosphors was discussed.By using thromoluminescence
it was found that the deterioration velocity of electroluminescent phosphors is determined by distribution of catching level.It was also showed that the deterioration velocity of electroluminescent phosphors is determined by salt halogen ion radius.The electroluminescent phosphors Were made by general way.The raw-min is fired in quartz tubes.which are surrounded by HBr
HCl or S atmosphere during flaring
respectively.We can conclude that the deterioration velocity of electroluminescent phosphors using HBr as atmosphere is slower than that at HCI and S atmosphere.
