摘要：

UV dye DMT-doped silica films were prepared by sol-gel process with dioxane as the cosolvent. Luminescence quenching was not observed even if the DMT concentration in the visibly transparent silica film is as high as 1.26 x 10(-2) M. The emission peaks centered at similar to375 nm for the films show red-shift of 35-45 nm, comparing with that of the cyclohexane solution of DMT. The fluorescence quantum efficiency of the films centered at similar to590 nm are larger than those at similar to375 nm. (C) 2002 Elsevier Science Ltd. All rights reserved.
