Process of preparing infrared-excitable sodium rare earth fluoride luminescent materials |
| 摘要 |
A hexagonal NaLnF4:Yb3<+>, Er3<+> (Ln represents the elements Y, La, Gd and/or Lu) has been found to be an efficient phospor emitting green light with infrared excitation, which can be prepared by firing a mixture of Na2SiF6 and coprecipitated Ln1-y-zYbyErzF3. Optimum firing conditions for synthesis of NaLnF4:Yb3<+>, Er3<+> have been found to be such that:
