Aluminoxane-epoxi-siloxane hybrids waveguides
(Elsevier B.V., 2008-11-01)
Boehmite-GPTS (GKS-glycidoxypropyltrimethoxysilane) hybrids (BGS) have been prepared by the sol-gel methodology. Spectroscopic properties and structural features have been evaluated from the initial sols to xerogels as a ...
Magnetic resonance study of a vanadium pentoxide gel
In this work we report results from continuous-wave (CW) and pulsed electron paramagnetic resonance (EPR) and proton nuclear magnetic resonance (NMR) studies of the vanadium pentoxide xerogel V2O5:nH(2)O (n approximate to ...
Random laser emission from a Rhodamine B-doped GPTS/TEOS-derived organic/silica monolithic xerogel
A Rhodamine B-doped 3-glycidoxypropyltrimethoxysilane (GPTS)/tetraethyl orthosilicate (TEOS)-derived organic/silica monolithic xerogel with excellent optical properties was prepared and its potential as a random laser host ...
