Luminescent properties of RE
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
