Abstract. Silica gels prepared by the sol-gel method with TEOS as a precursor and doped with the organic dyes rhodamine B, Na fluoresceine and eosine G were exposed to UV radiation pulses from a nitrogen laser. The absorption, luminescence and IR spectra were taken as a function of the exposure time. The absorption and the luminescence curves show successive maxima and minima. The same response is observed when the exposure procedure is repeated. These results are explained in terms of the cyclic filling and depletion of the long-lived triplet excited electronic state. At short exposure times, the data can be fitted with a Lorentzian curve and the corresponding parameters are given.

“…Moreover, anodized aluminum surface enhances luminescence of the rhodamine 6G dye by several times compared to porous glass [8]. The first experiments on lasing of organic compounds in anodized aluminum films obtained by sol-gel technology with adsorbed rhodamine dyes were performed in [9] under pumping by a pulsed N 2 laser with a pulse duration of 5 ns. Stimulated emission of rhodamine 6G in the porous matrix of anodized aluminum oxide was obtained in [10][11][12].…”

Spectral-luminescent and lasing characteristics of rhodamine 6G in porous aluminum oxide films anodized under various conditions are investigated. Lasing is obtained without external resonator in the longitudinal scheme under excitation by the second harmonic of Nd 3+ :YAG-laser radiation. The threshold pump power densities are in the range 3.5-15 MW/cm 2 depending on the anodizing conditions. Wherein, the lasing line narrows down from 12 to 5 nm.
