Pulsed cathodoluminescence of Nd³⁺: У₂O₃ ceramic synthesized from nanopowders obtained by laser evaporation of a solid target has been investigated in the 350-850-nm range. The samples were sintered in vacuum furnaces at temperatures of 1550-2050°C, but with different heating rates: 5K/min (first group) and 0.75K/min (second group). Strong luminescence bands of the Nd³⁺ ion showed up in the samples of the second group at λ≈425 and 457nm. A wide emission band at λ≈485nm of the intrinsic center predominates in the samples of the first group, while the luminescence bands of neodymium become weaker as the sintering temperature of the samples increases. It is shown that the appearance of the bands at λ≈425 and 457nm is associated with the presence in the ceramic of an impurity, most likely the monoclinic λ - У²O³ phase, concentrated in micron-size regions along the edges and at the junction points of the crystals.
