摘要
The emission spectra and lifetimes of R6G dye on silica-coated titania powder were studied. A dye could be shielded from a semiconductor surface by coating its surface with an insulating layer. Results showed that a lifetime of 3.25 ns for R6G on titania coated with 1 g silica/1 g titania was achieved.
