    ZnSe waa nooc jaale ah oo hufnaan ah oo mulit-cystal ah, cabbirka walxaha crystalline wuxuu ku saabsan yahay 70um, gudbinta kala duwan ee 0.6-21um waa doorasho aad u fiican oo loogu talagalay codsiyada kala duwan ee IR oo ay ku jiraan nidaamyada laser CO2 awoodda sare.
    Zinc Selenide waxay leedahay nuugista IR hoose.Tani waxay faa'iido u leedahay sawirka kulaylka, halkaasoo heerkulka walxaha fog laga ogaado iyada oo loo marayo spectrum shucaaca jirka madow.Daahfurnaanta hirarka dhererka dheer ayaa muhiim u ah sawiridda walxaha heerkulka qolka, kaas oo ka soo ifbaxaya hirarka ugu sarreeya ee ku dhawaad ​​10 μm oo leh xoog aad u hooseeya.
    ZnSe waxay leedahay tilmaame sare oo dib-u-gurasho taaso u baahan daahan ka-hortagga milicsiga si loo gaaro gudbin sare.Daahankayaga ballaaran ee AR waxaa lagu hagaajiyay 3 μm ilaa 12 μm.
    Walaxda Znse ee lagu sameeyay kaydinta uumiga kiimikada (CVD) asal ahaan ma jiraan nuugista wasakhaysan, waxyeelada kala firdhisashadu aad bay u yar tahay.Sababtoo ah nuugista iftiinka aadka u hooseeya ee dhererka hirarka 10.6um, markaa ZnSe waa walaxda doorashada koowaad ee samaynta walxaha indhaha ee nidaamka laser-ka ee Co2.Intaa waxaa dheer ZnSe sidoo kale waa nooc ka mid ah walxaha la isticmaalo ee nidaamka indhaha ee kala duwan ee gudbinta mowjadaha.
    Zinc Selenide waxa soo saara ka samaysan uumi Zinc iyo gaaska H2Se, oo ka samaysan sida xaashiyo dulmanayaasha Graphite.Zinc Selenide waa microcrystalline qaab dhismeedka, cabbirka hadhuudhka ayaa la xakameynayaa si loo soo saaro xoogga ugu badan.Single crystal ZnSe waa la heli karaa, laakiin ma aha mid caadi ah laakiin waxaa lagu soo warramey inuu leeyahay nuugista hoose oo sidaas awgeed waxtar badan u leh CO2 optics.

    Zinc Selenide oxidizes si weyn at 300 ° C, muujinaysaa qallafsanaanta balaastiig ah oo ku saabsan 500 ° C iyo kala qaybsanaan ku saabsan 700 ° C.Badbaadada, Daaqadaha Zinc Selenide waa in aan loo isticmaalin in ka badan 250°C jawiga caadiga ah.
