Abstract

Luminescence and absorption spectra of the silica samples prepared by a sol-gel technique and originally doped with Cu solutions in the range of 500/1-3000/1 are recorded. For alternatively applied CuCl₂ or Cu(AA)₂ dopants the same spectral profiles of dry solids are observed. A slightly structured emission band centered at 330 nm and ascribed to the 3d⁹4s¹ yields 3d¹⁰ transition of the Cu⁺ ion is recorded for excitation around 300 nm of samples previously dried and annealed below 455 K. The band shows a red shift for annealing at higher temperatures, and vanishes completely at 1173 K. Instead of broad emission band of more than double half width and of about 25 times higher intensity in the line center at 560 nm occurs most probably due to temperature dependent structural transition accompanied by the Cu⁺-Cu²⁺ change of the dopant valence.
