Abstract	In this study, red phosphors Ca$_{1−n }$Mg$_{ n }$TiO$_{3}$:Eu$^{3+}$,Bi$^{3+}$ were prepared by the sol–gel method and the impact of single dopant, co-dopants and solid solutions on the photoluminescence of the samples has been also investigated. Our results show that the crystal structure of the host does not have distinct changes when doped with Eu$^{3+}$, Bi$^{3+}$ and/or Mg$^{2+}$. The emission intensity at 615 nm of Eu$^{3+}$ increased at the presence of Bi$^{3+}$ ions owing to the energy transfer from Bi$^{3+}$ ion to Eu$^{3+}$ ion. Moreover, with the addition of Mg$^{2+}$, the red emission of the phosphor was further enhanced due to the stronger absorption at 399 and 467 nm, which match well with the emission of near-UV (395–400 nm) and blue-LED (450–470 nm), respectively. Under the near-UV (399 nm) or blue light (467 nm) excitation, the fluorescence quantum yield of the optimal composition Ca$_{0.9}$Mg$_{0.1}$TiO$_{3}$:0.18Eu$^{3+}$,0.018Bi$^{3+}$ is 0.36 and 0.41, respectively, which possesses the higher photoluminescence intensity than CaMoO$_{4}$:0.2Bi$^{3+}$,0.05Eu$^{3+}$ and the commercially available Y$_{2}$O$_{2}$S:Eu$^{3+}$ phosphors under near-UV excitation. Based on these results, we are currently considering the potential application of Ca$_{0.9}$Mg$_{0.1}$TiO$_{3}$:Eu$^{3+}$,Bi$^{3+}$ as a near-UV or blue-chip convertible red-emitting phosphor.
