Laser and fluorescence properties of dye-doped sol-gel silica from 400 nm to 800 nm

Lasing characteristics of Rhodamine B and Rhodamine 6G as a sensitizer in sol–gel silica

“…In the present work, dye-doped sol-gel silica samples have been fabricated following the sol-gel process of acid catalyzed hydrolysis/polycondensation [24][25][26][27][28][29][30][31][32][33][34][35]. Sol-gel silica samples of high optical homogeneity have been obtained.…”

Novel, Organically Doped, Sol-Gel-Derived Materials for Photonics: Multiphasic Nanostructured Composite Monoliths and Optical Fibers

“…In both cases photostability is a property of prime importance for selecting a laser dye. 75 In recent years lasing from dye-doped solid matrices has been demonstrated by several groups via a one-photon excitation process 21,22,[76][77][78][79][80] and even via a two-photon excitation process. 45,46 Excellent slope efficiencies (up to 39%) and lifetimes of sol-gel-processed solid-state dye lasers have been reported and it has been observed that ORMOSILs can exhibit longer lifetimes than in the solution state.…”

Effect of method of preparation and drying time on photophysical properties of coumarin 1 laser dye embedded in HCl catalysed sol–gel glasses

“…This defect limits their application in the UV and blue bands. Silica gel glasses have been used as solid host for solid state dye laser materials in recent research work to build solid state dye lasers in the UV and blue region because of their high transmittance and their high potential utility than polymers [4,5,[13][14][15][16][17][18][19][20][21][22][23][24][25]. For conventional glass production requiring high temperature which laser dyes cannot withstand, whereas the sol-gel reaction occurs at low/room temperature and therefore organic dye molecules can be incorporated in the gel network, with no risk of thermal degradation.…”
