ʻO Ultraviolet fluorescent anti-counterfeiting pauka (i kapa ʻia hoʻi i ʻike ʻia anti-counterfeiting pigment) he keʻokeʻo a ʻeleʻele paha ka hiʻohiʻona, ma o ka nalu o 200-400nm ultraviolet fluorescent lamp irradiation, hōʻike i ke kala māmā (fluorescent anti-counterfeiting ʻulaʻula, fluorescent anti-counterfeiting blue, ʻO ka melemele a me ka ʻōmaʻomaʻo fluorescent anti-counterfeiting), e waiho ana i ke kumu kukui uila uila ultraviolet i nalowale koke ke kala.
Hiki ke hoʻohana pinepine ʻia ka phosphor anti-counterfeit.
E like me ka like ʻole o ka nalu o ka excitation kumu, hiki ke hoʻokaʻawale ʻia ka pauka anti-counterfeiting fluorescent i ka nalu pōkole 254 nm, ka nalu lōʻihi 365 nm a me ka nalu ʻelua ultraviolet fluorescence.
ʻO nā hoʻololi kala fluorescence: kala ʻole - waihoʻoluʻu, waihoʻoluʻu - ʻālohilohi ke kala kumu, waihoʻoluʻu - ʻē aʻe.
ʻO ka UV anti - counterfeiting phosphor he maikaʻi ke kūpaʻa wai a me ke kūpaʻa wela, nā waiwai kemika paʻa, a me ke ola lawelawe o kekahi mau makahiki a i ʻole mau makahiki.
