The linear and non-linear properties of material have gained in both scientific interest and technological importance. Over the last few years, there has been much interest in developing materials with large nonlinearities in order to exploit their potential for use in ultrafast nonlinear optical devices. The different factors that play a role for controlling the refractive indices such as density, molar refraction, photon energy, coordination number, electronic polarizability, field strength of cations, bridging and nonbridging oxygen, and optical basicity are discussed in accordance with the obtained linear refractive index data. The nonlinear phenomena which include intensity dependent on refractive index, excitation energy, dispersion energy, optical energy, metallization criterion, second and third harmonic generations have been discussed. Finally, the optical application, viz. photonics, electro-optics, photo chromic and magneto-optics of the material have been studied.Keywords:Glass; linear; nonlinear indices; optical application

“…For instance, the photochromism and self-bleaching of silver halides contained glass, which is a classical PC glass discovered in the 1960s, originate from the transformation between silver ions and metal silver atoms. [18,19] Additionally, the reduction and oxidation reaction could happen in glass for some elements with various oxidation states (e.g., tungsten, [15] copper, [20,21] bismuth, [23] etc. ), resulting in the color change of the glasses.…”

Owing to the large storage capacity, the transparent luminescent glass with photo‐induced coloration properties has attracted considerable interest in recent years. However, lots of the photochromic (PC) mechanisms for glass are related to the ionic valence transformation, and the study associated with the defects‐induced photochromism of glass is limited. Herein, a kind of Sm3+ doped PC cadmium glass is fabricated, for which the PC mechanism is systematically investigated by various techniques, such as XPS spectra, thermoluminescence spectra, EPR spectra, etc. The results show that the mechanism of coloration for such glass should be due to the presence of oxygen vacancy‐related electron centers. Under 365 nm light irradiation, the color of the glass turns from colorless to brown, exhibiting a large color contrast, of 62%. Utilizing the re‐absorption process between absorption spectra and emission/excitation spectra, the emission intensity of Sm3+ is reversibly regulated, indicating their promising applications as an optical storage medium.

Transparent glass with photochromic and luminescent properties has recently garnered considerable interest in optical storage, while the photochromic transparent glass system is still limited. Herein, it is proposed that combining transparent glass matrix with photochromic nanocrystals is an efficient strategy to develop a broader range of photochromic luminescent glass systems. The Yb3+/Tb3+ co‐doped BaMgSiO4 glass ceramics are successfully prepared by a two‐step melt‐quenching approach followed by a thermal treatment in a reducing atmosphere. The glass ceramics exhibit high transparency and distinct coloration, showing a color change between colorless and pink by alternating irradiation between 365 nm ultraviolet light and 473 nm laser. The formation of color centers in the BaMgSiO4 nanoparticles drives the coloration of such glass ceramics. Based on their photochromic and photobleaching behavior, the efficient reversible upconversion luminescence modulation can be implemented with the maximum luminescence modulation rate of 79.83%. The excellent reproducibility and anti‐fatigue of such upconversion luminescence modulation demonstrate the promising application of Yb3+/Tb3+ co‐doped BaMgSiO4 glass ceramics as an optical storage medium.
