Dual-mode optical ratiometric thermometry using Pr

Owing to some special superior features, luminescence ratiometric thermometry has acquired popularity, particularly dual excitation single emission (SBR) and single excitation dual emission (FIR). Nonetheless, it remains difficult to create ratiometric thermometry that can operate in multiple modes. The integration of FIR and SBR techniques paves the way for advancements in various fields, including industrial processes, environmental monitoring, and biomedical applications, where accurate temperature measurements are crucial for optimal performance and safety. In this work, we describe a way to measure temperature based on the light-induced fluorescence of Pr
