Abstract:

A rhodamine derivative(ABDO) based on rhodamine 6G and diethylene triamine was synthesized and used as a fluorescent probe to detect temperature. The fluorescence spectra and ultraviolet-visible absorbant spectra were used to study the variation trend of ABDO-Er complex with the temperature. The stabilization time of ABDO-Er complex in constant temperature bath and fluorescence intensity of ABDO-Er complex, ABDO and rhodamine 6G with different temperature were studied. The results showed that ABDO-Er complex was directly proportional to temperature. Therefore, ABDO-Er complex could be used to monitor the change of environmental temperature.

Key words: Temperature, ABDO-Er complex, Fluorescence probe
