Abstract
Abstract This work reveals three structural factors for luminescent thermal quenching of Eu3+ in three molybdate-tungstate phosphors. The charge transfer state (CTS) energy level was found to play a major role in thermal quenching. The linkage configuration between the MoOx group and Eu3+ and the distortion of the MoOx group were regulatory factors, whereas the structural rigidity of the host had little impact. Phosphors applicable to near-ultraviolet excitable white light-emitting diodes (NUV-WLEDs) should exhibit thermally stable luminescence and effective absorption in the NUV region. Eu3+-doped molybdate-tungstate phosphors with MoO66− groups in the host matrix are potential candidates for NUV-WLEDs. However, they exhibit poor thermal quenching of Eu3+ luminescence. To obtain optimal properties, the roles of the CTS energy level, linkage configuration, distortion of MoOx groups, and structural rigidity were investigated in Eu3+-doped Sr2Ca(Mo/W)O6, Gd3B(Mo/W)O9, and Ca(Mo/W)O4. These phosphors possess typical 3D-connecting MoO66− groups, isolated MoO66− groups, and isolated MoO42− groups, respectively. This study offers a detailed analysis of the structural regulation of thermal quenching of Eu3+ luminescence.
