Abstract

In this Letter, we study diffuse reflectance and photoluminescence spectra for $O^{2 -}$ fully coordinated green-emitting ${Ce}^{3 +}$ and $N^{3 -}$ partially coordinated red ${Ce}^{3 +}$ in ${Ca}_{3} {Sc}_{2} {Si}_{3} O_{12} (CSS) : {Ce}^{3 +}$ , $N^{3 -}$ as a function of ${CeO}_{2}$ and ${Si}_{3} N_{4}$ contents in the raw material. Our results indicate that the presence of $N^{3 -}$ can enhance ${Ce}^{3 +}$ solubility in the form of red centers in CSS. At low ${Ce}^{3 +}$ concentration, green ${Ce}^{3 +}$ forms preferentially while red ${Ce}^{3 +}$ hardly forms even if $N^{3 -}$ content in the raw material is sufficient. There exists a threshold concentration of green ${Ce}^{3 +}$ ; only beyond that can color tunable luminescence with enriched red emission be achieved. Energy transfer from green ${Ce}^{3 +}$ to red ${Ce}^{3 +}$ is also studied, as only the green ${Ce}^{3 +}$ is excited by blue light.
