    New hole centers in natural quartz (1983)

    Notes: Abstract In natural citrines five new hole centers were detected and analyzed by electron paramagnetic resonance. An additional one was observed in rose-colored quartz crystals with radiation defects as the cause of coloration. Characteristic hyperfine patterns due to an adjacent aluminum impurity were resolved in the spectra of three of these centers. Their relations to other hole centers of well-known structure in quartz and fused silica are discussed and possible models for their structures are proposed.

    Two modified smoky quartz centers in natural citrine (1980)
    Springer
    Physics and chemistry of minerals 6 (1980), S. 145-156

    Notes: Abstract Electron paramagnetic resonance (EPR) measurements on natural citrine and greenish-yellow quartz revealed the presence of several localized hole centers adjacent to an aluminium impurity. The g tensors and their principal axes directions were determined for the two most prominent centers. The g-tensor variations and 27Al hyperfine splittings are roughly half as large as for the well-known smoky quartz centers. Optical and infrared absorption, thermal stability and thermoluminescence were also studied. In these citrine centers an additional defect must be present in the immediate neighborhood of the hole, but the exact nature of this defect is still unknown.
