摘要：

Very strong sharp lines in luminescence of Tm3+ have been observed in Li-codoped ZnS:Tm phosphor. In particular, blue emission intensity was stronger as compared with that of infrared emission when the codoped Li concentration in ZnS:Tm was 0.1 at.%. As ZnS:Tm emits a broad band and very weak TM3 + lines, the role of Li is proposed as follows: Li ions fill defects in the ZnS host, and hence excitation energy transfers from the ZnS host to Tm3+ very easily.
