摘要：It is 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 owing to the ultrafast non-radiation relaxation of vibration and collision of molecules in fluid matrixes. Here, a universal deep-eutectic-solvent strategy is proposed for developing pure organic phosphorescent fluid materials that are able to generate effective phosphorescent emissions at both room temperature (phi(RTP,293 K)approximate to 30 %) and even higher temperature (phi(RTP,358 K)approximate to 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 empowers the current organic phosphorescent system offering an alternative to determine moisture and heat from non-invasive photoluminescence emission colors.
