Ultraviolet fluorescent anti-counterfeiting pigment (yomwe imatchedwanso invisible anti-counterfeiting pigment) mawonekedwe ake ndi oyera kapena opanda mtundu, kupyolera mu utali wa 200-400nm ultraviolet fluorescent nyali kuwala, kusonyeza kuwala (fluorescent anti-bodza wofiira, fulorosenti odana ndi bodza, fulorosenti odana chinyengo chikasu ndi zobiriwira), kusiya ultraviolet fulorosenti kuwala gwero yomweyo mbisoweka mtundu.
Phosphor yotsutsa-yonyenga ingagwiritsidwe ntchito mobwerezabwereza.
Malingana ndi kutalika kosiyanasiyana kwa gwero lachisangalalo, fulorosenti yotsutsana ndi chinyengo ikhoza kugawidwa mufupikitsa 254 nm, mafunde aatali a 365 nm ndi mafunde awiri a ultraviolet fluorescence.
Kusintha kwa mtundu wa Fluorescence ndi: zopanda mtundu - mtundu, mtundu - mtundu wowala wowala, mtundu - mtundu wina.
UV anti - counterfeiting phosphor ili ndi kukana kwamadzi bwino komanso kukana kutentha, kukhazikika kwa mankhwala, komanso moyo wautumiki wazaka zingapo kapena makumi angapo.
