    ZnSe yog ib hom xim daj thiab pob tshab mulit-cystal khoom, qhov loj me me ntawm crystalline particle yog li 70um, kis ntau ntawm 0.6-21um yog qhov kev xaiv zoo rau ntau yam IR daim ntaub ntawv suav nrog lub zog loj CO2 laser tshuab.
    Zinc Selenide muaj qhov nqus qis IR tsawg. Qhov no yog qhov zoo rau kev ntsuas thermal, qhov twg kub ntawm cov khoom nyob deb yog paub dhau ntawm lawv tus neeg lub ntsej muag hluav taws xob hluav taws xob. Qhov ntev yoj yoj ntev yog qhov tseem ceeb rau kev ntsuas chav sov khoom, uas hluav taws xob thaum lub teeb hluav taws xob ntev li ntawm 10 μm nrog qhov siv tsawg heev
    ZnSe muaj qhov ntsuas ntawm qhov kub siab uas yuav tsum muaj cov tshuaj los tiv thaiv thiaj li ua tiav qhov kis tau zoo. Peb qhov dav dav AR txheej tau qhov zoo rau 3 tom txog 12 μm.
    Znse cov khoom tsim los ntawm cov tshuaj vapor deposition (CVD) ib txwm tsis muaj qhov tsis muaj lub zog haum, ua kom tawg yog qhov tsawg heev. Vim tias qhov qes qis heev rau 10.6um wavelength, yog li ZnSe yog qhov kev xaiv thawj cov khoom siv rau kev ua cov khoom kho qhov muag ntawm lub zog siab Co2 laser system. Tsis tas li ZnSe tseem yog hom siv cov khoom siv sib txawv rau cov kho qhov muag sib txawv hauv tag nrho kev xa xov kab ke.
    Zinc Selenide yog tsim los ntawm kev sib txuas los ntawm Zinc vapor thiab H2Se gas, ua cov ntawv ua ntawm Graphite susceptors. Zinc Selenide yog microcrystalline hauv cov qauv, cov noob nplej loj tau tswj hwm kom tsim tau lub zog tshaj plaws. Tib lub siv lead ua ZnSe muaj, tab sis tsis tshua muaj tab sis tau tshaj tawm tias muaj kev nqus qis thiab yog li muaj txiaj ntsig zoo dua rau CO2 optics.

    Zinc Selenide oxidizes zoo tshaj li ntawm 300 ° C, ua kom pom cov yas deformation ntawm kwv yees li 500 ° C thiab cuam tshuam txog 700 ° C. Kom muaj kev nyab xeeb, Zinc Selenide lub qhov rais yuav tsum tsis txhob siv ntau dua 250 ° C hauv cov huab cua ib txwm muaj.
