Zinc Selenide (ZnSe)

ʻO Zinc Selenide kahi hui melemele māmā me ka zinc a me ka selenium. Hana ʻia ia e ka synthesis o Zinc vapor a me H₂Se kinoea, hana ʻia e like me nā lau ma luna o kahi substrate graphite. Loaʻa iā ZnSe kahi helu o ka refraction o 2.403 ma 10.6 µm, ma muli o kāna mau hiʻohiʻona kiʻi maikaʻi loa, haʻahaʻa haʻahaʻa haʻahaʻa a me ke kūpaʻa kiʻekiʻe i ka haʻalulu wela, hoʻohana maʻamau ia i nā ʻōnaehana optical e hui pū me CO.₂laser (e hana ana ma 10.6 μm) me nā laser alignment HeNe inexpensive. Akā naʻe, he palupalu a hiki ke maʻalahi. ʻO kona laulā hoʻoili o 0.6-16 µm he mea kūpono ia no nā ʻāpana IR (nā puka makani a me nā lens) & no nā prisms ATR spectroscopic, a hoʻohana nui ʻia i nā ʻōnaehana kiʻi wela. Hoʻouna pū ʻo ZnSe i kekahi kukui ʻike ʻia a loaʻa haʻahaʻa ka absorption i ka ʻāpana ʻulaʻula o ka spectrum i ʻike ʻia, ʻaʻole like me germanium a me ke silika, no laila e ʻae ai i ka hoʻonohonoho ʻike maka.

ʻO Zinc Selenide ka hoʻohāhā nui ʻana ma 300 ℃, hōʻike i ka deformation plastic ma kahi o 500 ℃ a hoʻokaʻawale ma kahi o 700 ℃. No ka palekana, ʻaʻole pono e hoʻohana ʻia nā puka makani ZnSe ma luna o 250 ℃ i ka lewa maʻamau.

ʻO ka pakuhi ʻākau ka pihi hoʻouna o 10 mm mānoanoa, kahi pani ZnSe i uhi ʻole ʻia

Manaʻo kōkua: I ka hana ʻana me Zinc Selenide, pono e ʻaʻahu kekahi i nā mīkina lima, no ka mea he mea weliweli ka mea. No kou palekana, e ʻoluʻolu e hahai i nā kaʻina kūpono a pau, me ke komo ʻana i nā mīkina lima i ka wā e lawelawe ai i kēia mea a me ka holoi pono ʻana i kou mau lima ma hope.
