“…For the relation to hold value, the experimental and calculated values should be nearly identical and form a linear trend with a slope of 1. From Figure 1, it is seen that the previous assessment that the Gladstone–Dale relation holds reasonably well for silicate glasses is a valid assumption 36–63 . For the purpose of this discussion, measurements done at 589 and 589.3 nm were considered sodium D line values.…”

“…Therefore, it can be generally expected that the difference between the experimental index of refraction and the one calculated by the Gladstone–Dale relation should decrease with increasing wavelength. Unfortunately, this is not always the case, as seen in the top plot of Figure 3, which shows the average percentage error between the calculated index of refraction and experimentally measured one 34,36–63,72–112 . The overall average percentage error value in n was determined by averaging the percentage error of all glasses measured at a specific wavelength, while the average percentage error in n for each glass family was determined using only glasses in that family.…”

The Gladstone–Dale relation is among one of the many formulae put forward in the 19th century to try and relate the index of refraction and density of a material. Compared to other relations of the time, the Gladstone–Dale relation is advantageous as it is relatively simple to use. It has been suggested that the Gladstone–Dale relation can be used as a reliable way to calculate the index of refraction for oxide glasses because of the additive nature of the relation, making it ideal for glass compositions. The reliability of the Gladstone–Dale relation with regards to its use in glass science has been explored. Various oxide glass systems that use different network formers, conditional network formers, modifying oxides, and dopants have been obtained from the literature to determine the reliability of the relation with regards to index‐of‐refraction calculations. The benefits and faults of the relation are discussed, and it was found that it is not universally applicable for all glass compositions.

“…Among the various lanthanide species, the electronic behavior of cerium stands out: the interconversion between [Xe]4 f 1 (Ce(III)) and [Xe]4 f 0 (Ce(IV)) underlies the many applications of cerium‐based materials 8 . Cerium‐containing glasses have been suggested as Faraday rotators, 9,10 catalysts, 11 scintillators, 12 and super‐conductor components 13 . Furthermore, dopants of cerium play an important role as redox partner in photosensitive or photo‐stabilized glasses 14–17 .…”

Structure and properties of cerium phosphate and silicophosphate glasses

et al. 2022

We report on the fabrication, properties, and structure of cerium pyrophosphate glasses and partially substituted cerium silicophosphates. In those glasses, cerium occurs predominantly as Ce(III). A combination of dynamic nuclear magnetic resonance and electrical impedance spectroscopy is used to overcome the problem of assessing cerium speciation. While optical spectroscopy is unable to quantify the ratio of Ce(III)/Ce(IV) due to spectral overlap, proxy observations of the effect of silica‐for‐cerium substitution on optical extinction and the shape and width of the UV band gap corroborate vibrational spectroscopic data of the structural roles of cerium and silica. While silica bonding to phosphate units appears to stabilize Ce(IV), it also impedes the polaron transport, leading to higher polaron activation energy and lower electronic conductivity. On the other hand, Ce(III) is stabilized by coordinating to P = O.
