Ultraviolet fluorescent anti-counterfeiting ntụ ntụ (nke a na-akpọkwa na-adịghị ahụ anya mgbochi-ịghọta pigmenti) ọdịdị bụ ọcha ma ọ bụ ntụ ntụ na-enweghị ụcha, site na ogologo ogologo nke 200-400nm ultraviolet fluorescent oriọna irradiation, ngosi ìhè agba (fluorescent mgbochi adịgboroja acha anụnụ anụnụ, fluorescent mgbochi, counterfeiting. odo na akwụkwọ ndụ akwụkwọ ndụ na-egbochi fluorescent), na-ahapụ isi iyi ọkụ ultraviolet na-apụ n'anya ozugbo.
Enwere ike iji phosphor mgbochi adịgboroja mee ihe ugboro ugboro.
Dị ka dị iche iche wavelength nke excitation isi iyi, fluorescent anti-counterfeiting ntụ ntụ nwere ike kewaa n'ime mkpụmkpụ ife 254 nm, ogologo ife 365 nm na abụọ ife ultraviolet fluorescence.
Mgbanwe agba fluorescence bụ: enweghị agba - agba, agba - agba agba mbụ na-enwu, agba - agba ọzọ.
UV mgbochi adịgboroja phosphor nwere ezigbo nguzogide mmiri na nguzogide okpomọkụ, akụrụngwa kemịkalụ kwụsiri ike, yana ndụ ọrụ nke ọtụtụ afọ ma ọ bụ ọbụna ọtụtụ iri afọ.
