Uhlelo lomthombo wokukhanya wamaphoyisa we-Multi-band
Isakhiwo esiyisisekelo kanye nomgomo womthombo wokukhanya wamaqembu amaningi
Umthombo wokukhanya onamabhendi amaningi isistimu yokubona ehlukanisa ukukhanya okumhlophe okukhishwa umthombo kube amabhande ahlukene ngesethi eyodwa noma amabili yesihlungi sombala, bese ikukhipha ngomhlahlandlela wokukhanya.Ikakhulukazi iqukethe izingxenye ezinhlanu: umthombo wokukhanya, uhlelo lokuhlunga, uhlelo lokuphumayo, uhlelo lokubonisa lokulawula, kanye nekhabhinethi.(Bheka umfanekiso 1 ngesakhiwo).Phakathi kwazo, umthombo wokukhanya, isistimu yesihlungi, nesistimu yokukhiphayo izingxenye eziyinhloko zomthombo wokukhanya wamaqembu amaningi, ezinquma ukusebenza komthombo wokukhanya.Umthombo wokukhanya ngokuvamile usebenzisa isibani se-xenon, ukukhanya kwe-indium noma ezinye izibani zensimbi ze-halide ezisebenza kahle kakhulu.Isistimu yokuhlunga ibhekisela kakhulu kusihlungi sombala, kukhona izihlungi zombala eziboshiwe ezijwayelekile noma izihlungi zombala wokuphazamiseka kwebhendi yekhwalithi ephezulu.Ukusebenza kokugcina kungcono kakhulu kunokuqala, okunciphisa ngokuyinhloko umkhawulokudonsa onqunyiwe wokukhanya okunemibala, okungukuthi, i-monochromaticity yokukhanya okunemibala ithuthukiswa kakhulu.Ukumbozwa kwe-wavelength evamile kungu-350~1000nm, okuhlanganisa iningi lemigqa ye-spectral ku-ultraviolet yamaza amade, ukukhanya okubonakalayo kanye nezifunda eziseduze ne-infrared.
Umgomo wohlelo lokusebenza lomthombo wokukhanya wamabhande amaningi
1. Imithombo ye-Fluorescence kanye ne-multi-band light
Lapho ama-electron e-extranuclear ejabulile futhi egxumela esimweni sokujabula, ama-electron asesimweni esijabulile awazinzi futhi ahlale egxuma abuyele esimweni esiphansi ngamandla aphansi.Ngesikhathi sokugxuma, amandla atholiwe azokhishwa ngendlela yama-photons..Isenzakalo sokuthi into ethile ijatshuliswa ukuba ibe sesimweni sokujabula ngemva kokukhanyiswa yi-photon yobude obuthile be-wavelength, bese igxuma ibuyele ezingeni eliphansi lamandla ngokukhulula i-photon yolunye ubude begagasi obuthile.
Ibizwa nge-photoluminescence phenomenon, futhi isikhathi sokuphila se-photon ngokuvamile esikhishwa singaphansi kwesekhondi elingu-0.000001, elibizwa ngokuthi i-fluorescence;phakathi kuka-0.0001 no-0.1 wesekhondi, ibizwa ngokuthi i-phosphorescence.Uma into ikwazi ukuzijabulisa futhi ikhiqize i-fluorescence ngaphandle kokuvuswa kokukhanya kwangaphandle, kuthiwa into ine-intrinsic fluorescence.Esinye isimo se-fluorescence siwukukhiqiza amaza okukhanya anamaza ahlukene ahlukene ukusuka kumaza okukhanya asekuqaleni (imvamisa amaza amagagasi amafushane ukuze kukhiqizwe amaza amade) ngaphansi kwesasasa lomthombo wokukhanya wangaphandle, futhi ukubonakaliswa kwe-macroscopic ukukhipha okunye ukukhanya kombala.Umthombo wokukhanya onamabhande amaningi awukwazi ukuhlinzeka kuphela ngomthombo wokukhanya ophambene ukuze ubheke i-intrinsic fluorescence, kodwa futhi nomthombo wokukhanya ojabulisayo.
2. Umgomo wokuhlukanisa umbala
Umgomo wokuhlukaniswa kombala uyimfuneko yokukhethwa okulungile kwebhendi ye-wavelength (ukukhanya kombala) nesihlungi sombala somthombo wokukhanya wamabhande amaningi.kusho ukuthi ngokukhetha shades.
