Abstract

We computationally investigated the effects of oxygen and alkaline-earth on the emission wavelength of the $Eu^{2+}$-doped oxide phosphor. Using QSPR method, we found that the oxygen and alkaline-earth atom around the Eu atom increase and decrease the emission wavelength, respectively. We also investigated the $Eu^{2+}$-doped sulfide, nitride, and oxynitride phosphors.
