Umlinganiselo wokugcinwa kwepasi yokubona yeizibane zokuloba metal halidesesinye sezalathisi ezibalulekileyo zobuchwephesha bezibane zokuloba ze-metal halide.Ngokunyuka kwemfuno yezibane zokuloba ze-metal halide e-China kunye nokuphuculwa okuqhubekayo kwinqanaba lobugcisa, umlinganiselo wokugcinwa kwe-optical pass ye-metal halide izibane zokuloba zibaluleke ngakumbi nangakumbi.Eli phepha ligxininisa kwindlela kunye nokusebenza kohlalutyo olunzulu kunye nophando.
Uhlalutyo lokugcinwa kwentsimbi yokuloba i-halide pass light
Ukuzalisa uthotho lwe-metal halide, amandla ahlukeneyo, uyilo olwahlukileyo lolwakhiwo lwesibane se-metal halide isibane se-optic sigcina isantya sahlukile, njengokuloba kwesibane se-halide ekuqaleni kwesibane (iiyure ezingamakhulu amabini) isibini iiyure ukuya ︿ ukuguquguquka kwehle ngokukhawuleza, ukuqhubeka nokukhanya ukuhla kwe-flux ekhanyayo kugudileyo ngakumbi.Nangona kunjalo, kukwakho ezinye izibane zentsimbi zokuloba i-halide ezinegophe lokugcinwa kokukhanya okwahlukileyo, kunye nesantya sokuhla kwesantya sokukhanya kwindawo yokuqala yokutshisa ngokusisiseko siyafana naleyo kwindawo yokutshisa kamva.Umahluko ongasentla ubangelwa ikakhulu ngenxa yezizathu ezifanayo kodwa ezahlukeneyo zokuncipha kokukhanya kokukhanya kwithuba lokuqala nelisemva kwexesha lokutshisa.Ukuze uhlalutye ngakumbi oonobangela bokuncipha kokukhanya okuguquguqukayo kwindawo yomlilo yezibane ze-halide zetsimbi, kuyimfuneko ukuhlalutya indlela yokubola kokukhanya kwindawo yokutshisa kwangethuba nasemva kwexesha lezibane, ukuze kuphuculwe ngokufanelekileyo ukugcinwa kokudlula ukukhanya. izinga lezibane.
Okokuqala, indlela yokwehla kwe-flux kwindawo yokuqala yokutshisa iyahlalutywa.Ngokomzekelo, umbhobho we-arc ethileisibane sokuloba i-metal halideibandakanya: ubungakanani kunye nokumila kweqokobhe le-quartz bubble kunye ne-electrode;Ubude bokwandiswa kwe-Electrode;Ubushushu besiphelo esibandayo (kubandakanywa ubungakanani be-insulation coating kunye nobukhulu bokugquma);Emva kokuba umlinganiselo kunye nedosi yeepilisi zegolide ze-halogen ezizaliswe kunye negunya le-arc yokufaka igalelo, utshintsho lwe-optical transmittance lumiselwa ngokusisiseko: 1. Ukutshintshwa kwe-optical transmittance ye-quartz bubble shell.2. Utshintsho ekusebenzeni kwe-electrode emission (kubandakanywa nokuhla okunokwenzeka kwe-cathode).3. Utshintsho kwi-atomic concentration kunye nokusabalalisa kwe-athomu yezinto ezikhanyayo (Na, Sc, Dy, Hg-, njl.) kwiityhubhu ze-arc zezibane ze-metal halide.
Ekubeni iyonke ubushushu bemitha yeathom kwiphantsi kwamanzi metal halide isibane sokulobaityhubhu ye-arc ixhomekeke kugxininiso lweeathom ezivuyayo, intetho yayo ilandelayo:
N¿=Hayi(gk/g,)exp-(eVk/kT)·
Apho i-N0 lugxininiso lweatom yezinto ezahlukeneyo ezikhanyayo.I-Vk inamandla okuvuselela izinto ezahlukeneyo ze-luminescent.T liqondo lobushushu apho iiathom ze element nganye zikhoyo.Ekubeni kukho umahluko omkhulu wobushushu kumanqaku ahlukeneyo kwityhubhu ye-arc xa isibane se-metal halide sikwindawo yokucima, i-Figure 1 ibonisa umzobo we-isothermal curve we-arc tube ye-2000w isibane sokuloba i-metal halide.
Umzobo 1. Iprofayili yobushushu bePlasma yeI-2000w isibane sokuloba i-metal halide.Umgama we-electrode yi-4.2mm kwaye umgama we-isotherm yi-250K
Inokubonwa kule nxaki ingentla ukuba inani elifanayo leeathom ezikhanyayo zinokuqina okukhanyayo okwahlukileyo kwimimandla eyahlukeneyo ye-isotherm.Ukuxinwa kwe-NaI, i-ScI3 kunye nezinye iimolekyuli ze-metal halide kwimo yoxinzelelo lomphunga ohluthisiweyo umiselwa yiqondo lokushisa elibandayo le-arc ityhubhu, indawo yolwelo lwentsimbi ye-halide encanyathiselwe eludongeni lwetyhubhu yequartz kufutshane nesiphelo esibandayo (igqitywe yintsimbi. i-halide yokuzalisa inani, imilo kunye nemeko yendawo ebandayo yesiphelo) kunye nesantya sokuhamba nge-metal halide surface.Kuya kubonakala ukuba isiphelo esibandayo se-arc siya kuchaphazela kakhulu ugxininiso lwe-athomu kunye nokusabalalisa kombuso, ngokuqinisekileyo, kuya kuchaphazela ukuqina kwe-luminescence yesibane se-metal halide.Akunzima ukujonga i-liquid phase ye-metal halide distribution kufuphi nesiphelo esibandayo sesibane sokuloba i-metal halide kwindawo yokutshisa ngononophelo.Akukho nzima ukufumanisa ukuba ulwelo isigaba metal halide unikezelo kufutshane ekupheleni ebandayo metal halide isibane utshintsho kakhulu kwiiyure zokuqala ukuya amashumi iiyure indawo yokutshisa (ingakumbi Sc-Na series metal halide isibane).Ke ngoko, ukuhanjiswa koxinzelelo lweathomu kwityhubhu ye-arc kutshintsha kakhulu, esinye sezizathu eziphambili zokubola kokukhanya kokuqala kwesibane se-metal halide.
