New Synthetic Route to (3-Glycidoxypropyl)trimethoxysilane-Based Hybrid Organic−Inorganic Materials
TL;DR: In this paper, the effect of BF3OEt2 has been studied by multinuclear magnetic resonance (NMR) in the precursor sol and by Fourier transform infrared spectroscopy in the final material.
Journal ArticleDOI
Fluorescence study of zirconia films doped by Eu3+, Tb3+ and Sm3+ and their comparison with silica films
TL;DR: In this article, the advantages of zirconia films were discussed and Europium, terbium, and samarium were prepared by the sol gel method and deposited on quartz slides.
Journal ArticleDOI
Refractive index engineering of transparent ZrO2–polydimethylsiloxane nanocomposites
TL;DR: In this paper, a transparent ZrO2-polydimethylsiloxane (PDMS) nanocomposite with high refractive index was prepared by dispersing ZRO2nanoparticles in a PDMS matrix via ligand molecule engineering.
Journal ArticleDOI
Efficiency and photostability of dye-doped solid-state lasers in different hosts
TL;DR: In this article, the preparation procedures of pyrromethene and rhodamine dyes in silica, silica-zirconia, organically modified silicate (ormosil) and organic polymer matrices are surveyed.

The reactivity of TiO2 and ZrO2 in organically modified silicates
Gottfried Philipp,Helmut Schmidt +1 more
TL;DR: In this paper, the influence of titania, zirconia and silica on synthesis and properties of epoxide group containing organically modified silicates was investigated. But the results showed that the activity of silicon in both reactions is very poor.

Zirconia and Zirconia−ORMOSIL Planar Waveguides Prepared at Room Temperature
TL;DR: In this article, the authors describe the preparation of zirconia and hybrid Zirconians−ORMOSIL planar waveguides by sol−gel technology at room temperature.
Journal ArticleDOI
Sol‐gel glass waveguides prepared at low temperature
TL;DR: In this article, a planar waveguide of TiO2-organically modified silanes was prepared by the solgel method, either in a pure form or doped by red perylimide laser dye, and their optical properties characterized.
Journal ArticleDOI
Evanescent sensing in doped sol-gel glass films
John E. Lee,S. Scott Saavedra +1 more
TL;DR: Bromophenol blue, a pH indicator, was entrapped in porous glass films prepared by the sol-gel method and the colorimetric response of the films to pH was assessed visibly and by attenuated total reflectance spectrometry as discussed by the authors.
