| Description | Journal: Materials Research Express A series of $Eu^{3+}$ and $Tb^{3+}$ co-doped $CaMoO_{4}/SrMoO_{4}$ luminescent thin films were prepared by a facile solution method, and they were annealed at 550 °C for 2 h. The luminescent properties of the thin films were studied, which involve the energy transfer from $Tb^{3+}$ to $Eu^{3+}$. The emission color can be changed from green to red, with increasing $Eu^{3+}$ doping concentration in $Tb^{3+}$-doped $CaMoO_{4}/SrMoO_{4}$ thin films. In addition, it was observed that the PL intensity of $Eu^{3+}$ will enhance when $Tb^{3+}$ ions are incorporated into $Eu^{3+}$-doped $CaMoO_{4}/SrMoO_{4}$ thin films. The optical band gaps of the luminescent thin films are found to be in the range of 4.49 to 4.72 eV. These results revealed that $Eu^{3+}$ and $Tb^{3+}$ co-doped $CaMoO_{4}/SrMoO_{4}$ luminescent thin films have a significantly potential application in electroluminescent devices. |
