The optical properties of undoped RE2O3 (RE = Lu, Sc, Y) sesquioxides, which were prepared by different methods, are reported. Luminescent characteristics, including emission, excitation spectra as well as luminescence decay kinetics were studied in a wide spectral range. The main intrinsic emission bands are located in ultraviolet region and the origin of these luminescent bands is different owing to the different electronic structure. In present paper, the spectral characteristics of these samples are considered and compared with those studied before; the origin of the intrinsic bands is discussed.
