Coumarin Dyes

Laser dyes perylene red (p-red) or pyrromethene 567 (p567) were co-doped with coumarin 440 (C440) or coumarin 500 (C500) into MTES- and VTES-derived organically modified silicates (ORMOSILs) by sol-gel process. The effects of coumarin dye concentration on the laser performances of p-red and p567 were investigated. The results from laser efficiency measurements illustrated that at optimized coumarin concentration, the slope efficiency of co-doped p-red increased by a factor of 2 while that of co-doped p567 increased marginally. It was also found that by co-doping coumarin, the laser wavelength of p-red blue shifted and the laser thresholds for p567 and p-red could be reduced. The energy transfer mechanisms involved were also discussed.

N-La co-doped TiO2 has been synthesized via sol-gel process. The XRD result showed that the structure of N-La co-doped TiO2 was anatase. Their performance of photocatalytic degradation of methylene blue under visible light were investigated. The combined effects of catalyst compsition, calcination temperature, catalyst amount and reaction temperature on catalyst activity were investigated. Experiment results depicted that activeness of catalyst N2.5La0.5/TiO2 calcinated at 500°C for 2h was highest. Using this catalyst, when the catalyst amount was 0.35 g/L, the reaction temperature was 40°C the degradation rate of mehylene blue in 4h could reach 96.5%.
