Ibintu byera muri rusange bikurura gato urumuri rwubururu (450-480nm) mumucyo ugaragara (uburebure bwumurongo wa 400-800nm), bikavamo ibara ryubururu ridahagije, bigatuma rihinduka umuhondo muto, kandi bigaha abantu imyumvire ishaje kandi idahumanye kubera umweru wagize ingaruka.Kugira ngo ibyo bishoboke, abantu bafashe ingamba zitandukanye zo kwera no kumurika ibintu.
Hariho uburyo bubiri bukunze gukoreshwa, bumwe ni Garland yera, ni ukuvuga, kongeramo agace gato k'ibara ry'ubururu (nka ultramarine) kubintu byabanjirije kumurika, bitwikiriye ibara ry'umuhondo wa substrate mukongera kwerekana igice cy'urumuri rw'ubururu , bigatuma igaragara yera.Nubwo indabyo zishobora kwera, imwe igarukira, indi ni uko kubera igabanuka ryumubare wuzuye wumucyo ugaragara, umucyo uragabanuka, kandi ibara ryikintu rikaba umwijima.Ubundi buryo ni uguhumanya imiti, igabanya ibara na redox reaction hejuru yikintu hamwe na pigment, bityo byanze bikunze byangiza selile, kandi ikintu nyuma yo guhumeka gifite umutwe wumuhondo, bigira ingaruka kumyumvire.Ibikoresho byera bya Fluorescent byavumbuwe mu myaka ya za 1920 byagize intege nke zuburyo bwavuzwe haruguru kandi byerekana ibyiza bitagereranywa.
Fluorescent yera ni ikintu kama gishobora gukurura urumuri ultraviolet no gushimisha ubururu cyangwa ubururu-violet fluorescence.Ibintu bifite florescent yera yera yamamajwe birashobora kwerekana urumuri rugaragara rumurika kuri kiriya kintu, kandi nanone Urumuri rwinjira cyane rutagaragara rwa ultraviolet (uburebure bwumuraba ni 300-400nm) ruhinduka urumuri rwubururu cyangwa ubururu-violet rugaragara kandi rusohoka, kandi ubururu numuhondo ni amabara yuzuzanya. kuri buriwese, bityo ukuraho umuhondo muri matrix yingingo, ukagira umweru kandi mwiza.Kurundi ruhande, emissivitike yikintu kumucyo iriyongera, kandi ubukana bwurumuri rwasohotse burenze ubukana bwurumuri rwambere rugaragara ruteganijwe kubintu bigomba gutunganywa.Kubwibyo, umweru wikintu kibonwa namaso yabantu uriyongera, bityo ukagera kumugambi wo kwera.
Fluorescent yera ibintu nicyiciro cyibintu kama hamwe nuburyo bwihariye burimo guhuza kabiri guhuza hamwe na planarite nziza.Munsi yizuba, irashobora gukurura imirasire ya ultraviolet itagaragara mumaso (uburebure bwumuraba ni 300 ~ 400nm), igashimisha molekile, hanyuma igasubira mubutaka, igice cyingufu za ultraviolet kizashira, hanyuma kigahinduka urumuri rwubururu-violet n'imbaraga nke (uburebure bwa 420 ~ 480nm) bwasohotse.Muri ubu buryo, urugero rwerekana urumuri rwubururu-violet kuri substrate rushobora kwiyongera, bityo bikuraho ibyiyumvo byumuhondo biterwa numucyo mwinshi wurumuri rwumuhondo kugaragarira mubintu byumwimerere, kandi bikagaragara bitanga ingaruka yera kandi itangaje.
Kwera kwa florescent yera ni uburyo bwiza bwo kumurika no kuzuza ibara, kandi ntibishobora gusimbuza imiti kugirango itange umwenda "wera".Kubwibyo, niba umwenda ufite ibara ryijimye uvuwe na fluorescent yera gusa utabanje guhumanya, umweru ushimishije ntushobora kuboneka.Imiti rusange yo kumena imiti ni okiside ikomeye.Iyo fibre imaze guhumeka, ingirangingo zayo zizangirika ku rugero runaka, mugihe ingaruka zo kwera ziterwa na fluorescent umweru ni ingaruka nziza, ntabwo rero yangiza ingirangingo.Byongeye kandi, umweru wa fluorescent ufite ibara ryoroshye kandi ritangaje rya fluorescent mumirasire yizuba, kandi kubera ko ntamucyo ultraviolet uri munsi yumucyo mwinshi, ntabwo usa numweru kandi utangaje nko mumirasire yizuba.Umuvuduko ukabije wibintu byera bya fluorescent biratandukanye kubwoko butandukanye, kuko mugihe cyumucyo ultraviolet, molekile yumukozi wera izarimburwa buhoro buhoro.Kubwibyo, ibicuruzwa bivura hamwe na florescent byera byera bikunda kugabanuka byera nyuma yigihe kirekire cyizuba ryizuba.Muri rusange, urumuri rwihuta rwa polyester rumurika ni rwiza, urwa nylon na acrylic ni rwagati, naho ubwoya nubudodo buri munsi.
Umuvuduko ukabije ningaruka za fluorescente biterwa nimiterere ya molekuline yumubiri wera wa fluorescent, hamwe na miterere numwanya wabasimbuye, nko kwinjiza N, O, na hydroxyl, amino, alkyl, na alkoxy mumatsinda ya heterocyclic. , irashobora gufasha.Ikoreshwa mugutezimbere ingaruka za fluorescence, mugihe itsinda rya nitro nitsinda rya azo rigabanya cyangwa rikuraho ingaruka za fluorescence no kunoza umuvuduko wurumuri.
