METHOD OF PRODUCING NANOCOMPOSITE LUMINOPHOR IN FORM OF QUARTZ GLASS CONTAINING COPPER NANOCLUSTERS Russian patent published in 2012 - IPC C09K11/58 B82B3/00 C09K11/59 B82Y40/00 

FIELD: physics.

SUBSTANCE: copper ions are implanted into quartz glass with radiation dose of 5·10¹⁵-2·10¹⁷ cm^-2 and ion energy of 35-45 keV. The luminophor is then thermally treated in an air atmosphere at temperature 750-900°C for 1-2 hours, followed by treatment with ultraviolet radiation in the 240-260 nm wavelength range. The ultraviolet radiation source used can be an ultra-high pressure mercury lamp, a deuterium low-pressure lamp or a KrF excimer laser. Curve 1 shows the luminescence spectrum of a luminophor treated with a KrF excimer lamp, while curve 2 shows the luminescence spectrum of a luminophor treated with a low-pressure deuterium lamp and curve 3 shows the luminescence spectrum of a thermally treated luminophor without treatment with ultraviolet radiation.

EFFECT: high luminescence intensity and possibility of controlling the luminescence spectrum.
