Fluorimetry is a scientific and analytical technique used to detect and measure the fluorescent light emitted by the sample (lying in the visible spectrum) with the aid of ultraviolet rays. Here, the wavelength of the emitted light by the substance is greater than the absorbed light. This phenomenon is called luminescence (cold light).
Herein, we systematically categorize the currently reported fluorescence thermometers based on the aspects of fluorescence intensity and wavelength, reveal the …
