摘要

Abstract

Luminescent nanothermometry based on thermally coupled levels (TCLs) has emerged as a powerful tool for non-invasive temperature sensing

but it still lacks sufficient theoretical guidelines. To address this issue

a theoretical framework for Boltzmann luminescent nanothermometry has been established

which quantitatively defines the temperature window for establishing thermal equilibrium in TCLs

establishes a practical criterion for stable thermal coupling of TCLs

and enables predictive material design of temperature sensitivity. Based on this framework

a high sensitivity of 6.17% K

-1

is achieved

providing a theoretical basis for the rational design of high-precision nanothermometers.
