Abstract
It has become an accepted approach to construct room-temperature
phosphorescence (RTP) materials by suppressing the non-radiative decay process.
However, there is limited success in developing fluid phosphorescence materials
due to the ultrafast non-radiation relaxation of vibration and collision of
molecules in fluid matrixes. In this study, a universal strategy was proposed
for pure organic phosphorescent fluid materials that are able to generate effective
phosphorescent emissions at both room temperature (ΦRTP, 293 K ~
30%) and even higher temperature (ΦRTP, 358 K
~ 4.53%). Based on these findings, a qualitative analytical method was
developed for leak detection and a quantitative analytical technique was
further validated to help visually identify the heat distribution of irregular
surfaces. This advancement greatly empowers the current organic phosphorescent
system offering an alternative approach to determine moisture and heat from
non-invasive photoluminescence emission colors.
