Abstract:

Molecular dispersions of amorphous siliceous materials doped with organic molecules, TPPS, were prepared by a sol-gel process in which SOC2H54 was hydrolyzed in neutral solution. An amorphous silica which was doped with TPPS on the order Of lXl0-5 moImoI SiO2 showed photochemical hole burning at 4 K. The TPPSa-SiO2 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 up to 200 deg C.
