The Triplet State: Emerging Applications of Room Temperature Phosphorescence Spectroscopy

Room‐temperature phosphorescence (RTP) has been exploited for analytical research for over 30 years now due to the widespread recognition of its unique properties as a selective and sensitive technique, complementary to fluorescence. Recent years have seen the awakening of medical, geological, industrial, and technological interest in its application. The trend continues, driven by the achievements that have already been made and the promise of future achievements. This review attempts to cover specifically emerging applications of RTP in areas such as medicine, geological dating, forensics, and technology, illustrating the advantages that can be derived from the use of the technique and stressing its potential for novel applications.
