    I-ZnSe iwuhlobo oluthile lwe-mulit-cystal ephuzi futhi esobala, ubukhulu bezinhlayiya zamakristalu cishe zingama-70um, ukudlulisa uhla kusuka ku-0.6-21um kuyisinqumo esihle kakhulu sezinhlelo zokusebenza ze-IR ezahlukahlukene kufaka phakathi amasistimu aphezulu e-CO2 laser.
    IZinc Selenide inokufakwa okuncane kwe-IR. Lokhu kuzuzisa ukucabanga okushisayo, lapho amazinga okushisa wezinto ezikude etholwa nge-spectrum yemisebe yomnyama. Ukucaca isikhathi eside kwe-wavelength kubalulekile ezintweni zokushisa ekamelweni lokucabanga, ezikhanya ebangeni eliphakeme cishe le-10 μm ngamandla aphansi kakhulu.
    I-ZnSe inenkomba ephezulu yokuphikisa edinga ukugcotshwa okukhombisa ukufeza ukudluliswa okuphezulu. Ukumboza kwethu kwe-broadband AR kulungiselelwe i-3 μm kuya ku-12 μm.
    Izinto ze-Znse ezenziwe nge-chemical vapor deposition (CVD) empeleni azikho ukumuncwa kokungcola, ukusabalalisa umonakalo kuphansi kakhulu. Ngenxa yokumuncwa kokukhanya okuphansi kakhulu kwe-10.6um wavelength, ngakho-ke iZnSe iyinto yokuqala ongakhetha kuyo yokwenza izinto ezibonakalayo zohlelo lwe-CO2 laser enamandla amakhulu. Ngaphezu kwalokho i-ZnSe futhi iluhlobo lwezinto ezijwayelekile ezisetshenzisiwe zohlelo oluhlukile lwe-optical ku-waveband ehambisa lonke.
    I-Zinc Selenide ikhiqizwa yi-synthesis kusuka ku-Zinc vapor ne-H2Se gas, okwakha njengamashidi kuma-susceptors we-Graphite. IZinc Selenide iyi-microcrystalline esakhiweni, usayizi wokusanhlamvu ulawulwa ukukhiqiza amandla amakhulu. I-crystal eyodwa i-ZnSe iyatholakala, kepha ayijwayelekile kepha kubikwe ukuthi inokumunca okuphansi futhi ngaleyo ndlela iphumelela kakhulu kuma-CO2 optics.

    I-Zinc Selenide ixhuma kakhulu ku-300 ° C, ikhombisa ukuguqulwa kwepulasitiki cishe ku-500 ° C futhi kwehlukanise cishe ngo-700 ° C. Ukuphepha, amawindi eZinc Selenide akufanele asetshenziswe ngaphezu kwama-250 ° C endaweni ejwayelekile.
