Prediction of Thermal Coupled Thermometric Performance of Er ³⁺

摘要： Predicting thermometric performance for diverse materials will facilitate the selection and design of nanothermometers to meet complex environment and specific signal output with saving a lot of time and expense. Herein we explore and unveil the thermal coupled thermometric performance of Er3+/Yb3+ co-doped a set of host lattices via the chemical bond theory of complex crystals. The unknown B and ΔE values of the thermometry are accurately estimated by the chemical bond parameters, further deepening our cognition of the correlation between luminescence properties of Er3+ ions and microscopic crystal structure. This allows us to precisely forecast the thermal coupled thermometric performance of Er3+ for varying host lattices in advance.
