Kubungabunga byoroheje itara ryuburobyi (1)

Ikigereranyo cyo guhitamo neza cyaicyuma cya halide amatara yo kurobani kimwe mu bimenyetso byingenzi bya tekiniki byerekana amatara yo kuroba.Hamwe n’ibikenerwa n’amatara y’uburobyi y’icyuma mu Bushinwa no gukomeza kuzamura urwego rwa tekiniki, igipimo cyiza cyo gufata neza amatara y’uburobyi bw’icyuma kiragenda kirushaho kuba ingenzi.Uru rupapuro rwibanze ku buryo n'imikorere yo gusesengura byimbitse n'ubushakashatsi.

Gufata neza isesengura ryicyuma cya halide uburobyi

Kuzuza urukurikirane rw'icyuma igice, imbaraga zitandukanye, igishushanyo gitandukanye cyimiterere yamatara yicyuma cya halide optique igumana igipimo cyikigero kiratandukanye, nkinshi mubyuma byamatara ya halide kuroba mugitangira itara (amasaha magana abiri) couple ebyiri amasaha kugeza ︿ flux igabanuka vuba, komeza urumuri luminous flux kugabanuka biroroshye.Ariko, hariho kandi amatara yuburobyi yamatara hamwe nuburyo butandukanye bwo gufata neza urumuri, kandi igabanuka ryumucyo utangirira kumuriro wambere urasa cyane cyane nigihe cyo gutwika nyuma.Itandukaniro riri hejuru riterwa ahanini nimpamvu zisa ariko zitandukanye zo kugabanuka kwurumuri rwumucyo mugihe cyambere na nyuma yo gutwikwa.Kugirango turusheho gusesengura ibitera kugabanuka kwumucyo kugabanuka kumatara yicyuma cya halide, birakenewe gusesengura uburyo bwo kwangirika kwumucyo mumatara ya kare na nyuma yo gutwika amatara, kugirango tunoze neza uburyo bwo gufata neza urumuri igipimo cy'amatara.

Ubwa mbere, uburyo bwa flux bugabanuka kumwanya wambere wo gutwikwa burasesengurwa.Kurugero, arc tube ya runakaitara ryuburobyiikubiyemo: ingano nuburyo bwa quartz bubble shell na electrode;Uburebure bwa electrode;Ubukonje bwa nyuma bukonje (harimo ubunini bwa colasique nubunini bwa coating);Nyuma yikigereranyo na dosiye yuzuye ibinini bya halogene hamwe nimbaraga za arc zimaze kugenwa, ihinduka ryogukwirakwiza optique ryagenwe ahanini na: 1. Guhindura optique ya optique ya quartz bubble shell.2. Impinduka mubikorwa byohereza imyuka ya electrode (harimo na cathode ishobora kugabanuka).3. Impinduka muburyo bwa atome no gukwirakwiza atome yibintu bimurika (Na, Sc, Dy, Hg–, nibindi) mumiyoboro ya arc yamatara ya halide.

Kuva imirasire ya atome yuzuye murimunsi y'amazi icyuma cyo kurobaarc tube biterwa nubunini bwa atome zishimye, imvugo yayo niyi ikurikira:

N¿ = Oya (gk / g,) exp- (eVk / kT) ·

Aho N0 ni atomic yibanze yibintu bitandukanye.Vk nimbaraga zo gushimisha ibintu bitandukanye bya luminescent.T ni ubushyuhe aho atome ya buri kintu kiri.Kubera ko hari itandukaniro rinini ry'ubushyuhe ahantu hatandukanye mu muyoboro wa arc mugihe itara ryicyuma cya halide riri aho ryaka, Igicapo 1 kirerekana igishushanyo mbonera cya isothermal cuve ya arc tube ya 2000w itara ryuburobyi.

Igishushanyo 1. Ubushyuhe bwa plasma ya2000w icyuma cya halide itara ryo kuroba.Intera ya electrode ni 4.2mm naho intera ya isotherm ni 250K

Birashobora kugaragara uhereye kungingo yavuzwe haruguru ko umubare umwe wibintu bya luminous element atom bifite ubukana butandukanye bwumucyo mubice bitandukanye bya isotherm.Ubushuhe bwa NaI, ScI3 nizindi molekile ya halide ya molekile yumuvuduko wumwuka wumuyaga bigenwa nubushyuhe bwa nyuma bwubukonje bwumuyoboro wa arc, ubuso bwicyuma cya halide yubuso bufatanye nurukuta rwa quartz hafi yimbeho ikonje (bigenwa nicyuma igice cyuzuye cyuzuye, imiterere nuburyo bwubuso bukonje) hamwe numuvuduko w umuvuduko unyuze hejuru yicyuma cyamazi.Birashobora kugaragara ko impera ikonje ya arc izagira ingaruka cyane kuri concentration ya atome no gukwirakwiza, birumvikana ko bizagira ingaruka kumurabyo wa luminescence yamatara ya halide.Ntabwo bigoye kwitegereza icyiciro cyamazi yicyuma gikwirakwizwa hafi yubukonje bwicyuma cya halide itara ryuburobyi ahantu ho gutwika witonze.Ntabwo bigoye kubona ko gukwirakwiza icyuma cyamazi ya halide ikwirakwizwa hafi yubukonje bwamatara yicyuma cya halide ihinduka cyane mumasaha ya mbere kugeza kumasaha icumi yumuriro (cyane cyane itara rya Sc-Na ryicyuma cya halide).Kubwibyo, gukwirakwiza atomike muri arc tube ihinduka cyane, nimwe mumpamvu nyamukuru zituma urumuri runini rwangirika rwamatara ya halide.
