Patterning of dye-doped mesostructured silica thin films and lasing actions in their films

Abstract

Highly-ordered, transparent, 2-dimensional hexagonal mesoporous silica thin films have been synthesized by an acidic sol-gel self-assembly chemistry using a triblock copolymer as surfactant and aging as-made samples under water vapor hydrothermal conditions. Using the mesoporous silica films as support, the patterning of rhodamine 6G-doped mesostructured silica can be made by soft lithography. The laser actions in the waveguides are investigated in this report.
