2.3 Kedu ogige ụwa na-adịghị ahụkebe nwere ike ịnweta ụzarị infrared?
N'ime ihe ndị na-adịghị ahụkebe nke ụwa, lanthanum hexaboride na lanthanum boride nwere nano nwere ike ịmịkọrọ ụzarị infrared.Lanthanum hexaboride (LaB6)bụ ihe a na-ejikarị eme ihe na radar, aerospace, electronics ụlọ ọrụ, ngwá ọrụ, ngwá ọrụ ahụike, ụlọ ngwa metallurgy, gburugburu ebe obibi, na ubi ndị ọzọ. Karịsịa, lanthanum hexaboride otu kristal bụ ihe eji eme tubes elektrọn dị elu, magnetrons, beam elektrọn, ion ion, na cathodes ngwa ngwa.
Na mgbakwunye, nano-scale lanthanum boride nwekwara ihe onwunwe nke ịmịkọrọ ụzarị infrared. A na-eji ya na mkpuchi n'elu ihe nkiri polyethylene iji gbochie ụzarị infrared site na ìhè anyanwụ. Mgbe ị na-amịkọrọ ụzarị ọkụ infrared, nano-scale lanthanum boride anaghị anabata oke ọkụ a na-ahụ anya. Ihe a nwere ike igbochi ụzarị ọkụ infrared ịbanye na iko windo na ihu igwe na-ekpo ọkụ, ma nwee ike iji ọkụ na ọkụ ọkụ na-arụ ọrụ nke ọma na ihu igwe oyi.
A na-eji ihe ndị na-adịghị ahụkebe ụwa eme ihe n'ọtụtụ mpaghara, gụnyere agha, ike nuklia, teknụzụ dị elu, na ngwaahịa ndị ahịa kwa ụbọchị. Dịka ọmụmaatụ, a na-eji lanthanum na-emeziwanye arụmọrụ tactical nke alloys na ngwá agha na akụrụngwa, a na-eji gadolinium na isotopes ya dị ka ndị na-etinye neutron na mpaghara ike nuklia, a na-ejikwa cerium dị ka ihe mgbakwunye iko iji nweta ultraviolet na ụzarị infrared.
Cerium, dị ka ihe mgbakwunye iko, nwere ike ịmịkọrọ ultraviolet na ụzarị infrared ma ugbu a ejiri ya mee ihe na iko ụgbọ ala. Ọ bụghị nanị na ọ na-echebe megide ụzarị ultraviolet kamakwa ọ na-ebelata okpomọkụ n'ime ụgbọ ala, si otú ahụ na-azọpụta ọkụ eletrik maka ntụ oyi. Kemgbe 1997, agbakwunyere iko ụgbọ ala Japan na cerium oxide, ma jiri ya na ụgbọ ala na 1996.
3.Njirimara na ihe na-emetụta mmetụta nke infrared absorption site na ogige ígwè
3.1 Ngwongwo na ihe na-emetụta mmetụta nke absorption infrared site na ogige metal gụnyere akụkụ ndị a:
Ọnụego nnabata: Ọnụ ọgụgụ nnabata nke ogige ígwè na ụzarị infrared dịgasị iche dabere na ihe ndị dị ka ụdị ígwè, ọnọdụ elu, okpomọkụ, na ogologo ogologo nke ụzarị infrared. Ọla ndị a na-ahụkarị dị ka aluminom, ọla kọpa, na ígwè na-enwekarị ọnụego nnabata nke ụzarị infrared n'etiti 10% na 50% n'ime ụlọ okpomọkụ. Dịka ọmụmaatụ, ọnụego nnabata nke elu aluminom dị ọcha na ụzarị ọkụ infrared na ụlọ okpomọkụ bụ ihe dịka 12%, ebe ọnụọgụ nke elu ọla kọpa siri ike nwere ike iru ihe dịka 40%.
3.2 Ngwongwo na ihe na-emetụta ihe ntinye infrared site na ogige ígwè:
Ụdị ọla: ọla dị iche iche nwere usoro atọm dị iche iche na nhazi eletrọn, na-eme ka ikike ha dị iche iche dị iche iche maka ụzarị infrared.
Ọnọdụ dị n'elu: Ihe siri ike, oyi akwa oxide, ma ọ bụ mkpuchi nke elu igwe ga-emetụta ọnụ ọgụgụ absorption.
Okpomọkụ: Mgbanwe okpomọkụ ga-agbanwe ọnọdụ eletrọnịkị n'ime igwe ahụ, si otú ahụ na-emetụta nnabata ya nke ụzarị infrared.
Infrared wavelength: Ogologo ebili mmiri dị iche iche nke ụzarị infrared nwere ikike nnabata dị iche iche maka ọla.
Mgbanwe n'okpuru ọnọdụ akọwapụtara: N'okpuru ọnọdụ ụfọdụ akọwapụtara, ọnụego nnabata nke ụzarị infrared site na ọla nwere ike ịgbanwe nke ukwuu. Dị ka ihe atụ, mgbe a na-eji ihe pụrụ iche kpuchie elu ígwè, a pụrụ ime ka ike ya nwee ike ịmịkọrọ ụzarị ọkụ infrared. Na mgbakwunye, mgbanwe na ọnọdụ eletrọnịkị nke ọla na gburugburu oke okpomọkụ nwekwara ike iduga mmụba na ọnụego nnabata.
Ngwa ngwa: Njirimara absorption nke infrared nke ogige ọla nwere uru ngwa dị mkpa na teknụzụ infrared, foto thermal, na mpaghara ndị ọzọ. Dịka ọmụmaatụ, site n'ịchịkwa mkpuchi ma ọ bụ okpomọkụ nke elu igwe, enwere ike ịhazi nnabata ya nke ụzarị infrared, na-ekwe ka ngwa na nha okpomọkụ, ihe ngosi ọkụ, wdg.
