LiF Substrate Definition
LiF (lithium fluoride) substrates suna nufin kayan da aka yi amfani da su azaman tushe ko goyan baya don aiwatar da jigon fina-finai na bakin ciki daban-daban a cikin fagagen gani, photonics da microelectronics.LiF kristal ne mai bayyanawa kuma mai tsananin rufewa tare da faffadan bandeji.
LiF substrates ana amfani da su a cikin aikace-aikacen fina-finai na bakin ciki saboda kyakkyawar fa'ida a cikin yankin ultraviolet (UV) da tsayin daka ga zafi da halayen sinadaran.Sun dace musamman don aikace-aikace irin su kayan shafa na gani, jigon fim na bakin ciki, spectroscopy da microscopy na lantarki.
LiF substrates yawanci ana zaɓar su azaman kayan ƙasa saboda suna da ƙarancin ɗaukar nauyi a cikin kewayon UV kuma suna da santsi don ingantacciyar ma'auni ko lura.Bugu da ƙari, LiF yana nuna kwanciyar hankali mai kyau a yanayin zafi mai girma kuma yana iya jure wa fasahohin ajiya da yawa kamar ƙawancen zafi, sputtering, da ƙananan katako na kwayoyin halitta.
Kaddarorin kayan aikin LiF sun sa su dace musamman don aikace-aikace a cikin abubuwan gani na UV, lithography, da crystallography na X-ray.Babban juriya ga abubuwan muhalli da kwanciyar hankali na sinadarai ya sa su zama kayan aiki iri-iri don aikace-aikacen bincike da masana'antu daban-daban.

LiF (lithium fluoride) sananne ne don kyawawan kayan infrared (IR) azaman kayan gani don tagogi da ruwan tabarau.Anan akwai wasu mahimman bayanai game da lu'ulu'u na gani na LiF2:
1. Fahimtar Infrared: LiF2 yana nuna kyakkyawan haske a cikin yankin infrared, musamman ma a cikin tsaka-tsakin infrared da nisa.Yana iya watsa haske a cikin kewayon tsayin kusan 0.15 μm zuwa 7 μm, yana sa ya dace da aikace-aikacen infrared iri-iri.
2. Low sha 1: Lif2 yana da karfin sha a cikin abin da aka harba, yana ba da ƙarancin ɗorewa na haskakawa ta hanyar.Wannan yana tabbatar da babban watsawa kuma don haka ingantaccen watsawa na infrared radiation.
3. Babban maƙasudin ƙididdigewa: LiF2 yana da babban ma'auni mai mahimmanci a cikin kewayon raƙuman infrared.Wannan dukiya tana ba da damar ingantaccen sarrafawa da sarrafa hasken infrared, yana mai da shi mahimmanci ga ƙirar ruwan tabarau waɗanda ke buƙatar mayar da hankali da lanƙwasa radiation infrared.
4. Wide bandgap: LiF2 yana da babban bandgap na kusan 12.6 eV, wanda ke nufin yana buƙatar shigarwar makamashi mai girma don fara canjin lantarki.Wannan dukiya tana ba da gudummawa ga babban fa'ida da ƙarancin sha a cikin ultraviolet da yankuna infrared.
5. Ƙarfafawar thermal: LiF2 yana da kwanciyar hankali mai kyau na thermal, wanda ke ba shi damar yin tsayayya da yanayin zafi mai zafi ba tare da lahani mai mahimmanci ba.Wannan yana sa ya dace da aikace-aikacen da suka haɗa da fallasa zuwa yanayin zafi mai zafi, kamar tsarin hoto mai zafi ko firikwensin infrared.
6. Chemical Juriya: LiF2 yana da juriya ga yawancin sinadarai, ciki har da acid da alkalis.Ba ya amsawa ko ƙasƙanta cikin sauƙi a gaban waɗannan abubuwan, yana tabbatar da dorewa da amincin na'urorin gani daga LiF2.
7. Ƙananan birefringence: LiF2 yana da ƙananan birefringence, wanda ke nufin ba ya raba haske zuwa jihohi daban-daban.Wannan kadarar tana da mahimmanci a aikace-aikacen da ke buƙatar yancin kai na polarization, kamar a cikin interferometry ko wasu ingantattun tsarin gani.
Gabaɗaya, LiF2 ana girmama shi sosai don kyakkyawan aikin sa a cikin bakan infrared, yana mai da shi abu mai mahimmanci don tagogi da ruwan tabarau a cikin aikace-aikacen infrared iri-iri.Haɗin sa na babban fahimi, ƙananan sha, babban bandgap, kwanciyar hankali na thermal, juriya na sinadarai, da ƙananan birefringence yana ba da gudummawa ga kyakkyawan aikin infrared.
