In order to correlate how the solvent affects emission properties of fluorescent dyes, the fluorescence emission spectra of carboxytetramethylrhodamine (TAMRA) and rhodamine B (RhB) as well as myoglobin conjugated with TAMRA were measured in methanol, polyvinyl alcohol (PVA) polymer matrix, trehalose and trehalose/sucrose sugar glass matrices. The fluorescence properties and spectral shifts observed in the TAMRA and RhB spectra were compared and analyzed to provide information on the environment and dynamics of the matrices. The fluorescence spectra of myoglobin conjugated with TAMRA in sugar glasses were examined to gain insight into the behavior of protein in sugar films. Efforts were also made to discern the changes in fluorescence characteristics, e.g. the fluorescence intensities and emission maxima, depending on the drying condition of films, thereby revealing the effect of residual water in the films.
