Abstract

Near-infrared emission material, ${\rm{C}}{{\rm{e}}^{3 +}}$, ${\rm{E}}{{\rm{r}}^{3 +}}$ co-doped ${\rm{C}}{{\rm{a}}_{1.5}}{{\rm{Y}}_{1.5}}{\rm{A}}{{\rm{l}}_{3.5}}{\rm{S}}{{\rm{i}}_{1.5}}{{\rm{O}}_{12}}$ has been synthesized via a high-temperature solid-state reaction method. The luminescence intensity of 1532 nm emission excited with 455 nm increases 4.2 times after the introduction of ${\rm{C}}{{\rm{e}}^{3 +}}$ ions because of ${\rm{C}}{{\rm{e}}^{3 +}} \to {\rm{E}}{{\rm{r}}^{3 +}}$ radiation-reabsorption energy transfer and nonradiative energy transfer sensitization as well as the ${}^4{{\rm{I}}_{11/2}}({\rm{E}}{{\rm{r}}^{3 +}})\; + {\;^2}{{\rm{F}}_{5/2}}({\rm{C}}{{\rm{e}}^{3 +}}){\to ^4}{{\rm{I}}_{13/2}}({\rm{E}}{{\rm{r}}^{3 +}}) + {\rm{C}}{{\rm{e}}^{3 +}}{(^2}{{\rm{F}}_{7/2}})$ cross relaxation between ${\rm{C}}{{\rm{e}}^{3 +}}$ and ${\rm{E}}{{\rm{r}}^{3 +}}$ ions. The result shows that the developed material is convenient to obtain high-efficiency, near-infrared emission using a commercial blue GaN LED as a pumping source.
