The recombination luminescence from Zn imperfections has been extensively investigated; however, there have been few reports on the long persistent luminescence of Zn imperfections as emitting centers. Here, we observed a long persistent luminescence in blue-white visible region from 6 ZnO:3 GeO 2 :Al 2 O 3 phosphor with Zn imperfections as emitting centers. Persistent luminescence...
Here, we report for the first time the optical properties of Bi2+ and Tm3+ co-doped germanate glasses and elucidate the potential of this material as substrates to improve the performance of CdTe solar cell. A strong emission peak at 800nm is observed under the excitation of 450–700nm in this material. The energy transfer processes from the transitions of Bi2+ [2P3/2(1)→2P1/2]: Tm3+ [3H6→3H4] are...
