Аннотация

Objects of the study were colorless single crystals of quartz with a total amount of impurities lesser than 1%. Implantation of vanadium ions into the quartz structure was carried out parallel to the symmetry axis C. Irradiation doses varied from 0.75 × 1017 to 1.5 × 1017 ion/cm2. With the purpose to anneal radiation defects and to redistribute the implanted vanadium admixture, the post-implanting heat treatment was carried out in the air atmosphere, within the range 200–1000 °C. There was solved issue of ion-beam modification of the colorimetric properties of the quartz matrix with simultaneous control of change in the nature of color of the piezo quartz raw material. In result of the study, samples with annealing temperatures of 383 and 585 °C were investigated most thoroughly by methods of adsorption optical spectroscopy. The quartz sample with annealing temperature 383 °C has acquired an olive-green color due to formation of oxide nanoprecipitates of vanadium ions with different valences: V2+, V3+, V4+. The quartz sample with annealing temperature 585 °C become discolored in result of oxidation of vanadium ions and their transition in the pentavalent state V5+.
