Temperature effects on the solid-matrix luminescence properties of 4-phenylphenol adsorbed on filter paper.
Experimental values of fluorescence quantum yield, phosphorescence quantum yield, and phosphorescence lifetime were obtained at temperatures from 23 degrees to -180 degrees for 4-phenylphenol adsorbed on filter paper. From the experimental values, rate constants for phosphorescence and radiationless transition from the triplet state were calculated along with the triplet formation efficiency. The data revealed several important aspects that are responsible for the room-temperature fluorescence and phosphorescence of 4-phenylphenol adsorbed on filter paper.
