A Minireview of the Natures of Radiation-Induced Point Defects in Pure and Doped Silica Glasses and Their Visible/Near-IR Absorption Bands, with Emphasis on Self-Trapped Holes and How They Can Be Controlled

<table>Pulsed-X-ray-induced spectra of a pair of optical fibers with pure silica cores, one with high-OH and the other with low-OH, decomposed to emphasize bands centered near 1.6 eV unique to low-OH fiber [<a href="/journals/physri/2013/379041/#B33">33</a>]. Note rapid room-temperature decay of these metastable visible/near-IR bands.</table>
