Smoky coloration of quartz caused by bound small hole polaron optical absorption

Abstract The dominant visible absorption band of smoky SiO2 is attributed to a light induced transfer of holes captured at O2− ions near Al3+ on Si4+ sites from one to an equivalent O2− site, the excitation acting against the self-induced trapping potential.
