METHOD OF DETECTION OF NANO-SIZE FRACTION OF CRYSTALS OF SODIUM FLUORIDE ON SUBSTRATE Russian patent published in 2009 - IPC G01N21/66 B82B1/00 

FIELD: physics, measuring.

SUBSTANCE: use concerns field of the analysis of materials. The essence of the method consists that detection of the nano-size fraction of crystals of sodium fluoride is performed by measuring of dose dependence of a light output of pulsing cathode luminescence S_k of analysed yields of plasma or laser pulverisation on a substrate and the subsequent comparison gained dose dependences S_k with the dose dependences of light outputs of a pulsing cathode luminescence for reference nano-size and volume crystals S_k ^nano (etalon) and S_k ^volume (etalon) accordingly.

EFFECT: possibility of determination nano-size fraction of crystals of sodium fluoride in the nanocrystalline coats on substrates in yields of a plasma or laser pulverisation of crystals of fluoride of sodium without application of electronic microscopes.
