Thermal activation induced charge transfer state absorption redshift realizes strong anti-thermal quenching in Pr 3+ -activated phosphor

In our work, a totally anomalous thermal quenching phenomenon of red-shifted and enhanced charge transfer state (CTS) absorption is found for the first time in LiTaO : Pr phosphors. The crystal structure, luminescent properties and the mechanism of abnormal thermal quenching were investigated in det...

Zusammenfassung:In our work, a totally anomalous thermal quenching phenomenon of red-shifted and enhanced charge transfer state (CTS) absorption is found for the first time in LiTaO : Pr phosphors. The crystal structure, luminescent properties and the mechanism of abnormal thermal quenching were investigated in detail.
