초록

We investigated the emission property of Ce 3+ and Tb 3+ co-doped CaHfO 3 phosphor. Using photoluminescence and photoluminescence excitation spectroscopy, we found that as a result of the energy transfer from Ce 3+ to Tb 3+ , the visible emission intensity of Tb 3+ increased dramatically with near ultraviolet (UV) light excitation, and consequently, the colors of our phosphors were tuned from blue to green/yellow and through to white. The temperature dependent emission measurement revealed that the energy transfer from Ce 3+ to Tb 3+ in the near UV region could be more efficient at low temperatures. © 2019 Elsevier B.V.
