Photoreflectance (PR) spectra have been measured at room temperature for single crystals of CuAlxGa1-xSe2 alloys grown by the chemical vapor transport method. Exciton transition energies related to valence-to-conduction bands at room temperature (EA, EB and EC in eV) have been determined as a function of composition as EA = 2.654x + 1.674(1 - x) - 0.22x(1 - x), EB = 2.767x + 1.749(1 - x) - 0.17x(1 - x) and EC = 2.923x + 1.972(1 - x) - 0.32x(1 - x). The PR results are discussed in terms of PL spectra.
