Abstract

We both theoretically and experimentally investigated the luminescence wavelength control of the $Eu^{2+}$-doped $CaAlSiN_3$ (CASN:$Eu^{2+}$). To modify emission wavelength, Na-doped and Mg-doped CASN:$Eu^{2+}$ (NCASN:$Eu^{2+}$ and MCASN:$Eu^{2+}$) have been studied. According to quantum chemistry calculation result, we synthesized NCASN:$Eu^{2+}$ and MCASN:$Eu^{2+}$. NCASN:$Eu^{2+}$ and MCASN:$Eu^{2+}$ showed shorter emission wavelength than that of CASN:$Eu^{2+}$.
