    • Note, however, that the measurements of optical spectra, particularly of optical absorption in the ultraviolet region, are much more difficult in the powdered samples as compared to optically clear bulk silica glass. Therefore the positions of the broad absorption bands, calculated from the diffuse reflectance spectra, may be uncertain up to ±0.2 eV.

    • 2 is preferable (see Ref. [117]). Using the latter correction, the calculated f value for the 5.8 eV absorption would be 1.36 times larger. For consistency, however, the traditional form of Smakula's formula is used in the present paper.

    • 2-centers and 5.4 eV band in α-quartz should be regarded as tentative [32], since after the initial work [49] no subsequent closer studies were undertaken.

    • note
    • Some caution must be excercised, however, with the reasoning that centers in neutron-irradiated quartz are necessarily isolated Frenkel defects in otherwise ideal crystal lattice. Site-selective studies of NBOHCs in neutron irradiated quartz [17] indicate a glass-like disorder around considerable fraction of the defect sites. A comparison between the 7.6 eV bands in oxygen-deficient glass and γ-irradiated quartz would be more correct.

    • The term 'inhomogeneous broadening' denotes here the dispersion of center properties caused both by the quasi-continuous glassy disorder and by the more discrete perturbations, caused by compositional inhomogeneity due to substitutions in the second or more remote coordination spheres of ODC.

    • note
    • The shape of the excitation spectrum follows closely the contour of the 7.6 eV absorption band in samples of low-oxygen deficiency [92], [93] and deviates from it in oxygen deficient [76] or γ-irradiated [165] samples. At least a part of this effect can be attributed to shape distortions due to the high optical density of oxygen-deficient or irradiated samples in this region.

    • The assumption that the PL of the 'fast' fraction is quenched at higher temperatures is supported by the reported [94] stronger dependence of the 4.4 eV PL on temperature when excited at 7.7 eV (decrease ∼10 times between 50 and 250 K) as compared to the case of 5 eV excitation (decrease ∼3 times).
