“…Two characteristic absorption bands with maxima at about 430 and 620 nm are observed.The positions of the absorption bands are relatively constant and do not show any change, whereas their peak heights changed, suggesting that only the population of the defects is affected by the irradiation dose. Similar results have been obtained with gamma and x-ray irradiation on sodalime silica glasses[10,11]. The absorption bands of 620 and 430 nm have been attributed to the absorption of NBOHCs[1,3,9,12,13], NBOHC1 correlating with the absorption band of 430 nm and NBOHC2 correlating with the absorption band of 620 nm.…”

This paper reports the effects of gamma ray irradiation and glass composition on the optical and infrared spectra of quaternary silicate glasses. Experimental results reveal the formation of radiation-induced absorption bands in the visible region attributed to nonbridging oxygen hole centres. The band gap energy and the width of the energy tail above the mobility gap have been measured before and after irradiation. The decrease in the energy gap values has been discussed in terms of radiation-induced structural modifications and the glass composition. Changes in the infrared spectra with progressive gamma irradiation have been observed and explained with reference to the radiolysis of Si–O–Si bonds.

“…In the case of exchanged samples, an additional emission is observed, consisting of a broad band extending from 600 to 800 nm. Emission bands of Ag + 2 , Ag 2+ 3 and Ag + 3 molecular clusters have been observed in various glasses [16][17][18][19]. The mean position of these band may vary from 600 to 700 nm depending on the matrix composition and their spectra of optical absorption (or luminescence excitation curves) consist of broad peaks centred around 340, 395 and 450 nm.…”

Thin films of silica containing 0.15 at.% Eu and 3.5 to 7 at.% Na were prepared by sol-gel chemistry and annealed at 600 • C in air, then submitted to ion-exchange treatments in NaNO 3 : AgNO 3 for studying the effect of the plasmon resonance of Ag nanoparticles on the excitation of Eu 3+ ions. When excited at other wavelengths in the UV other than that corresponding to the 7 F 0 -5 L 6 transitions of the Eu 3+ ions, the yield of the 5 D 0 -7 F 2 emission is increased by a factor of the order of 10 in films containing Ag particles with respect to that in non-exchanged films.

“…At present the colorization of LAS glass ceramics has been becoming a research hotspot in this field. Macalik [10] studied the effects of Fe, Co and Mn on crystallization and structure of lithium aluminosilicate glass ceramic. ZHANG Zhi-Yong [11] investigated the effects of Cr 2 O 3 , CoO, NiO, MnO 2 and heating process on colorization of LAS glass ceramics.…”

The effect of single coloring agent Nd(NO 3) 3 on the crystallization, microstructure and colorization of Li 2 O-Al 2 O 3-SiO 2 (LAS) glass ceramics were investigated by differential thermal analysis (DTA), X-ray diffractometry (XRD) and scanning electron microscopy (SEM). The introduction of little neodymium has no effect on the crystallization manner and the formation of main crystallization phase, but more neodymium will weaken the crystallization of LAS glass. Little neodymium can increase the glossiness of LAS glass ceramic, while more neodymium can color LAS glass with light purple or red purple. The colorability of neodymium for LAS glass ceramic decreases with the increase of crystallization temperature.
