An innovative way of obtaining room-temperature phosphorescence signals in solution

This manuscript presents an innovative way of obtaining room temperature phosphorescence (RTP) in solution. For the first time, the RTP of naphthalene derivatives have been observed in solution without using any kind of organized media. The RTP signals are a consequence of intermolecular protection when analytes are exclusively in the presence of a heavy atom salt and sodium sulfite is employed as an oxygen scavenger to minimize RTP quenching. A rigorous study of numerous experimental and instrumental variables has been carried out.
