Abstract:

Pulsed cathodoluminescence of Nd3+:Y2O3 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 degrees C, but with different heating rates: 5 K/min (first group) and 0.75 K/min (second group). Strong luminescence bands of the Nd3+ ion showed up in the samples of the second group at lambda approximate to 425 and 457 nm. A wide emission band at lambda approximate to 485 nm 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 lambda approximate to 425 and 457 nm is associated with the presence in the ceramic of an impurity, most likely the monoclinic lambda-Y2O3 phase, concentrated in micron-size regions along the edges and at the junction points of the crystals.
