Electron spin resonance in glasses
TLDR
A review of electron spin resonance (ESR) studies in glasses can be found in this paper, where transition-group ions, radiation-induced defect centers, ferromagnetic precipitates, and photo-induced centers are discussed.Abstract:
The present paper reviews a quarter of a century of electron spin resonance (ESR) studies in glasses. Specific subtopics addressed include transition-group ions, radiation-induced defect centers, ferromagnetic precipitates, and photo-induced centers. For brevity, most of the examples in the first three categories are confirmed to the familiar oxide glass systems and only the most concrete conclusions are elaborated. The section treating radiation-induced defects is further abridged in light of several reviews of this topic in the current literature. Even within these limitations of scope, a great diversity of material is summarized. Most of the studies cited provide information concerning the atomic scale structure of the host glasses and several have immediate impact on practical problems ranging from glass technology to geochemistry.read more

Defect structure of glasses: Some outstanding questions in regard to vitreous silica
TL;DR: In this paper, the defect structure of glasses is discussed primarily in the context of vitreous silicon dioxide (v-SiO2) and a unified picture of radiation-damage processes is formulated for high-purity silicas of both low and high-OH contents.

Spin-hamiltonian formalisms in electron magnetic resonance (emr) and related spectroscopies
Czesław Rudowicz,Sushil K. Misra +1 more
TL;DR: The spin-Hamiltonian concept is briefly outlined to set a framework for definitions of relevant terms in this article, and the historical development leading to, and the current status of, the spin- Hamiltonian (SH) formalisms characterizing electron magnetic resonance (EMR), also referred to as electron paramagnetic (or spin) resonance (EPR or ESR), is reviewed.

Irradiation induced defects in glasses resulting in the photoionization of polyvalent dopants
Doris Möncke,Doris Ehrt +1 more
TL;DR: In this article, the extent of solarization is strongly influenced by many factors such as glass matrix, dopants, or irradiation source, which can be detected with optical and EPR spectroscopy.

Characterization of three E'-center variants in X- and γ-irradiated high purity a-SiO2
TL;DR: In this article, the existence of three E'-center variants of high purity amorphous silicas (a-SiO2) following irradiation by 100 keV X-rays at 77 K or 60 Co γ-rays (∼1 MeV) near 300 K was investigated.
