Ultraviolet fluorescent anti-counterfeiting pauda (i kapa ʻia hoʻi i ʻike ʻia anti-counterfeiting pigment) he keʻokeʻo a i ʻole ka pauka kala ʻole, ma o ka nalu o 200-400nm ultraviolet fluorescent kukui irradiation, hōʻike i ke kala māmā (fluorescent anti-counterfeiting ʻulaʻula, fluorescent anti-counterfeiting ʻulaʻula, fluorescent anti-counterfeiting blue, fluorescent anti-counterfeiting ʻōmaʻomaʻo, ʻōmaʻomaʻo ʻōmaʻomaʻo ʻōmaʻomaʻo. nalo kala.
Hiki ke hoʻohana pinepine ʻia ka phosphor anti-hoʻopunipuni.
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.
