“…Presented below are the structural formulas of some dyes: SiO 2 matrices were synthesized using sol-gel method by the hydrolysis of TEOS (or TMOS) with addition of nitric acid as a reaction catalyst [26,27]. The alcohol solutions of the dyes (LD1, LK678, Rh800 in ethanol; LD2 in ethanol with added 1 mM HNO 3 ; DCM in methanol) were introduced after 30 min.…”

We synthesized a series of sol-gel silica matrices doped with laser dyes DCM, LK678, LD1, and LD2 which alcohol solutions have efficient lasing in the red spectral region and Rh800-in the near infrared (NIR) one. Absorption, fluorescence, and laser properties of the dyes in silica samples prepared by sol-gel process were investigated. It has found some peculiarities in preparation process of the laser matrices and in spectral characteristics of the dyes in these matrices. IntroductionThe lasers tuned in the red and the near infrared (NIR) regions of the spectrum and dyes-sensitizers for this spectral range are widely applied for diagnostics of different biological and medical objects. For instance, an oxazine dye [1] is used for early diagnostics of Alzheimer's disease. The urgency of laser sources for this region is due to the fact that the penetration depth of the radiation into living tissue for them is about a centimeter. Furthermore study of new photosensitizers with the silica coating for photodynamic therapy at infrared excitation [2] necessitates quest of new radiation sources.Dye lasers developed specially may be used for this purpose. However, for many practical applications solid-state dye lasers are the most challenging because of they are not required bulky dye-flow systems, and no toxic and inflammable solvents [3]. Matrices prepared by the sol-gel process, polymeric ones or porous glasses are used in these lasers.

“…Solgel processed materials have been used in areas ranging from novel solid-state lasers to platforms for chemical sensors and biosensors. [15][16][17][18][19][20][21][22] Also, the sol-gel technique has been used to fabricate nonlinear optically active composites for applications in optical telecommunications. 5 Organically modified and sol-gel-processed materials have also been shown to exhibit excellent nonlinear optical (2) and (3) properties.…”

“…It has been demonstrated that the colorants retain many of their optical properties inside these solids [1]. Laser dyedoped sol-gels are being actively studied because of their potential applications as tunable solid-state laser sources [2][3][4][5][6]. In this work, the optical behavior of SiO2 gels doped with rhodamine B, Na fluoresceine and eosin G, when exposed to UV-light, is reported.…”

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.
