A series of Eu3+-Bi3+ co-doped CaMoO4 red phosphors were synthesized via the solid-sate reaction method. The crystal structures of the obtained samples were identified by X-ray powder diffraction (XRD). The photoluminescence property was investigated, and the results showed that the intensity of excitation spectra and emission spectra could be changed with different doping ratios of Bi3+/Eu3+. The proposed explanation of these changes was from the energy transfer between Bi3+ and Eu3+ and the unbalanced charge from the substitution of Eu3+ and Bi3+ for Ca2+ in CaMoO4. The obtained samples are a promising red light emitting phosphor for the needs of different excitation sources with near-UV and blue GaN-based chips. |
