Visible red random lasing in Y[sub 2]O[sub 3]:Eu[sup 3+]/ZnO polycrystalline thin films by energy transfer from ZnO films to Eu[sup 3+]
M. K. Chong, A. P. Abiyasa, K. Pita, and S. F. Yu
Visible red random lasing centered at ~611 nm has been observed in YO:Eu/ZnO films at room temperature. Using a 355 nm laser source to excite the ZnO films, ultraviolet (UV) random lasing has been observed. The UV lasing spectrum can be tuned to overlap strongly with the F-L excitation spectrum of ...
