摘要：
The electronic structure and optical properties of a red phosphor, Y2O3:Eu, have been studied using the first-principles molecular-orbital and band-structure methods. Using the calculated one-electron energy levels, several properties of the host material and properties of the phosphor based on host-impurity interactions have been explained. However, it has been found that the luminescence properties of Eu3+ require the spin-orbit effects to be included in the computational methods.
