A. Pillonnet et al., Fluorescence of Cr3+ doped alumina optical waveguides prepared by pulsed laser deposition and sol-gel method, J LUMINESC, 87-9, 2000, pp. 1087-1089
The fluorescence properties of Cr3+ in optical waveguides of doped alumina
prepared by sol-gel or pulsed laser deposition (PLD) are compared with thos
e of Cr-doped alumina powders obtained by sol-gel method and having gamma,
theta and alpha crystalline phases. Cr3+ is located in gamma crystallites i
n sol-gel films but the three phases are present in PLD films. (C) 2000 Els
