I-Zinc Selenide (ZnSe)

I-Zinc Selenide iyinhlanganisela ephuzi-ephuzi, eqinile ehlanganisa i-zinc ne-selenium. Idalwe ngokuhlangana komhwamuko weZinc kanye ne-H₂I-se gas, eyakha njengamashidi ku-graphite substrate. I-ZnSe inenkomba ye-refraction engu-2.403 ku-10.6 µm, ngenxa yezimpawu zayo ezinhle kakhulu zokuthwebula izithombe, i-coefficient ephansi yokumuncwa kanye nokumelana okuphezulu nokushaqeka okushisayo, ivamise ukusetshenziswa ezinhlelweni zamehlo ezihlanganisa i-CO.₂i-laser (esebenza ku-10.6 μm) enamalaser okuqondanisa e-HeNe angabizi. Nokho, ithambile futhi izonwaya kalula. Ibanga lokudluliswa kwayo elingu-0.6-16 µm liyenza ilungele izingxenye ze-IR (amawindi namalensi) kanye namaprism e-ATR abonwayo, futhi asetshenziswe kabanzi kumasistimu wokuthwebula ashisayo. I-ZnSe iphinde idlulise ukukhanya okubonakalayo futhi ibe nokumunca okuphansi engxenyeni ebomvu ye-spectrum ebonakalayo, ngokungafani ne-germanium ne-silicon, ngaleyo ndlela ivumela ukuqondanisa okubonakalayo.

I-Zinc Selenide i-oxidizes kakhulu ku-300 ℃, ikhombisa ukuwohloka kwepulasitiki cishe ku-500 ℃ futhi ihlukanisa cishe no-700 ℃. Ngokuphepha, amawindi e-ZnSe akufanele asetshenziswe ngaphezu kuka-250 ℃ endaweni evamile.

Amacebiso: Uma usebenza ne-Zinc Selenide, umuntu kufanele ahlale egqoke amagilavu, lokhu kungenxa yokuthi impahla iyingozi. Ukuze uphephe, sicela ulandele zonke izinyathelo zokuphepha ezifanele, okuhlanganisa ukugqoka amagilavu lapho uphethe le nto kanye nokugeza izandla zakho kahle ngemva kwalokho.

Ukuze uthole imininingwane eningilizayo eningiliziwe, sicela ubuke ikhathalogi yethu yokubona ukuze ubone ukukhetha kwethu okuphelele kwe-optics eyenziwe nge-zinc selenide.
