Paper Abstract

Molecular dispersions of amorphous siliceous materials doped with organic molecules, TPPS, were prepared by a sol-gel process in which Si(0C2H5)4 was hydrolyzed in neutral solution. An amorphous silica which was doped with TPPS on the order of 1x105 mol/mol Si02 showed photochemical hole burning at 4 K. The TPPS/a-Si02 was heat-treated at various temperatures and the change of optical spectrum were observed as a function of temperature. It was found that the sample was comparatively stable upto 200 °C.
