UV/Vis absorption, emission, and excitation spectroscopy with various solvents (dimethyl sulfoxide (DMSO), N,N-Dimethylformamide (DMF), and tetrahydrofuran (THF) and Acetone) at two concentrations (10−4 and 10−5) Mol/L were used to investigate the spectra and photophysical properties of Acridone. Using the integrated emission spectra, the fluorescence quantum yields are calculated. The emission maxima were determined using the red absorption band’s positions and bandwidths. The maximum absorption and emission wavelengths were found to be 390–399 nm and 399–413 nm, respectively, resulting in Stokes shifts of 318.05 and 1142.62 cm-1. Fluorescence spectra have a broad spectral range so that as concentration is increased, each peak shifts toward a long wavelength. It has been discovered that as concentrations increase, the quantum efficiency decreases. The fluorescence quantum yield magnitude is affected by solvents, with THF having the highest value.
