Abstract
In this work, a novel thermometry strategy based on the diversity in thermal quenching behavior of two intervalence charge transfer (IVCT) states in oxide crystals is proposed, which provides a promising route to design self‐referencing optical temperature sensing material with superior temperature sensitivity and signal discriminability. Following this strategy, uniform Tb 3+ /Pr 3+ :NaGd(MoO 4 ) 2 micro‐octahedrons are directionally synthesized. Originated from the diverse thermal responses between Tb 3+ ‐Mo 6+ and Pr 3+ ‐Mo 6+ IVCT states, fluorescence intensity ratio of Pr 3+ to Tb 3+ in this material displays excellent temperature sensing property in a temperature range from 303 to 483 K. The maximum…
