Fluorescent dye (DCM-OH) is covalently bridged to organic-inorganic hybrid material to prevent molecular stacking and to get high fluorescence efficiency and laser property. Novel DCM-OH is synthesized to have hydroxyl functional groups and is bridged to trialkoxysilane as a sol-gel precursor. It participates in sol-gel process to synthesize dye-bridged organic-inorganic hybrid material (dye-bridged hybrimer) and solid-state dye laser sample is ready through polymerization. Fluorescence property of dye-bridged hybrimer is compared with DCM-doped hybrimer that is simple mixture of DCM-OH and hybrimer matrix. The covalently bridged structure of hybrimer with DCM-OH prevented the stacking of fluorescent molecules and enhanced concentration stability. The dye-bridged hybrimer shows much higher fluorescence intensity and low color-shift until it reached high concentration in comparison with DCM-doped system. And the proper lasing property is observed in dye-bridged hybrimer samples.
