METHOD OF PRODUCING NANOCOMPOSITE LUMINOPHORE IN FORM OF QUARTZ GLASS CONTAINING COPPER AND TITANIUM NANOCLUSTERS Russian patent published in 2012 - IPC C09K11/58 B82B3/00 C09K11/59 C09K11/67 B82Y20/00 

FIELD: physics.

SUBSTANCE: copper and titanium ions are implanted into quartz glass with radiation dose of 5×10¹⁵ - 2×10¹⁷ cm² and current density of 10 mcA/cm², followed by thermal treatment of the luminophore in an air atmosphere at temperature 750-900°C for 1-2 hours. Copper ions are implanted at ion energy of 35-40 keV and titanium ions are implanted at ion energy of 40-45 keV. After thermal treatment, the luminophore is treated with UV radiation with wavelength 240-260 nm. The UV source used can be a 100-200 W ultra-high pressure mercury lamp with luminous efficacy of 30-40 lm/W, a 400 W low-pressure deuterium lamp or a 300 W KrF excimer laser with wavelength 248 nm.

EFFECT: high stability of luminescence spectrum and possibility of controlling said spectrum.
