A white long-lasting phosphor Y2O2S:Tb, Sm: an improvement of Y2O2S:Tb

As an improvement of reported Y2O2S:Tb3+, a white-light long-lasting phosphor: Y2O2S:Tb3+, Sm3+ was prepared by the solid-state reaction. The photo-luminescence spectra showed that the position and shape of Tb3+ and Sm3+ emissions under UV excitation were similar in this host, which ensured a stable...
