Ultraviolet fluorescent anti-counterfeiting hmoov (tseem hu ua invisible anti-counterfeiting pigment) tsos yog dawb los yog xim tsis muaj xim, los ntawm lub wavelength ntawm 200-400nm ultraviolet fluorescent teeb irradiation, tso saib lub teeb xim (fluorescent anti-counterfeiting liab, fluorescent anti-xws li xiav, fluorescent anti-xeb daj thiab ntsuab), tawm hauv ultraviolet fluorescent teeb qhov chaw tam sim ntawd ploj xim.
Anti-phosphor cuav tuaj yeem siv ntau zaus.
Raws li qhov sib txawv wavelength ntawm excitation qhov chaw, fluorescent anti-xws li hmoov yuav muab faib ua luv yoj 254 nm, ntev yoj 365 nm thiab ob yoj ultraviolet fluorescence.
Fluorescence xim hloov yog: tsis muaj xim - xim, xim - thawj xim ci, xim - lwm yam xim.
UV tiv thaiv - phosphor cuav muaj cov dej tsis zoo thiab kub tsis kam, cov khoom siv tshuaj lom neeg ruaj khov, thiab kev pabcuam lub neej ntawm ntau xyoo lossis ntau xyoo.
