Five different refraction formulas were applied to SiO 2 polymorphs in order to determine the most suitable refractive index-density relation. 13 SiO 2 polymorphs with topological different tetrahedral frameworks are used in this study including eight new low density SiO 2 polymorphs — so called "...
Anti-reflective SiO2 thin films with low refraction index were prepared via traditional sol-gel process followed by light or furnace heat treatment.The microstructure of SiO2 particles in the sol was exactly controlled by adopting appropriate organic dopant and silane coupling agent in the ...
Therefore, the the formation of gradual refraction index from front sur- reflection of the front surface can be significantly reduced. Scientific Reports | 5:11375 | DOI: 10.1038/srep11375 3 www.nature.com/scientificreports/ Figure 4. A photograph (a) and a SEM image of a monolayer PS ...

the variation in the index of refraction n presents a minimum in the case of films growth at 7 min, while the frequency of the dominant IR active bond-stretching vibration at about 1075 cm1 follow an inverse trend having a maximum in the case of oxide films processed for 7 min. ...
The oxidation-temperature-dependent index of refraction of bulk SiO 2 films obtained using the proposed model agrees well with independent one-layer model data on oxides which have thicknesses around the first half-cycle of ellipsometry thickness, for which the interlayer effect is minimal. It is ...
Films were characterized for their thickness, index of refraction, and photoluminescence at room temperature. Photoluminescence yield is strongly enhanced for vacuum annealing in the temperature range 500 - 750 degrees C. Reasonable room-temperature photoluminescence is also observed for annealing at 1000 ...

The variation of the refraction index in the simulated optical spectra lead to a very high values, such as above 2.0 (Figure 10 middle panel). Such high refraction index values are not expected in the glass under the study as the densest component, ZnO, has a refraction index that is not...
