Iftiinka infrared wuxuu leeyahay saameyn kuleyl ah oo weyn, kaas oo si fudud u horseedaya kororka heerkulka deegaanka.Muraayadaha dhismaha ee caadiga ah ma laha wax saameyn ah oo kuleyl ah kaas oo lagu gaari karo oo kaliya hababka sida filimada.Sidaa darteed, dusha sare ee muraayadaha dhismaha, filimka baabuurta, goobaha dibadda, iwm waxay u baahan yihiin inay isticmaalaan qalabka kuleylka kuleylka si loo gaaro saameynta kuleylka kuleylka iyo badbaadinta tamarta.Sanadihii la soo dhaafay, tungsten oxide ayaa soo jiidatay dareenka baahsan sababtoo ah sifooyinka sawir-qaadista ee aadka u fiican, iyo budada tungsten oxide ee cesium-doped tungsten oxide waxay leedahay sifooyin nuugista oo aad u xoog badan oo ku yaal gobolka infrared, isla mar ahaantaana, gudbinta iftiinka muuqda ayaa sarreeya.Cesium tungsten budada bronze hadda waa budada nano aan organic oo leh awoodda nuugista ugu dhow ee infrared-ka ugu fiican, sida walaxda kuleylka hufan iyo tamar-badbaadinta cagaarka iyo walxaha deegaanka, waxay leedahay rajooyin ballaaran oo codsi ah oo ku saabsan xannibaadda infrared, kulaylka galaaska. dahaarka iyo baabuurta kale iyo dhismayaasha.

Nano cesium tungsten bronze,cesium-doped tungsten oxide Cs0.33WO3ma aha oo kaliya in uu leeyahay sifooyinka nuugista xooggan ee gobolka u dhow-infrared (mawjadaha 800-1100nm), laakiin sidoo kale waxay leedahay sifooyin gudbinta xooggan ee gobolka iftiinka muuqda (mawjadaha 380-780nm), iyo gobolka ultraviolet (mawjadaha 200-380nm). ) waxa kale oo uu leeyahay sifooyin gaashaan oo adag.

Diyaarinta dhalada Dahaarka leh ee CsxWO3

Ka dib markii budada CsxWO3 ay si buuxda dhulka u dhigto oo ultrasonically kala firdhiso, waxaa lagu daraa 0.1g / ml polyvinyl aalkolada PVA, walaaqay biyaha 80 ° C 40 daqiiqo, iyo ka dib gabow 2 maalmood, duub duub muraayadda caadiga ah (7cm). *12cm) *0.3cm) Waxaa lagu dahaadhay si loo sameeyo filim khafiif ah si loo helo dhalada dahaarka ah ee CsxWO3.

Imtixaanka waxqabadka kuleylka kuleylka ee dhalooyinka dahaarka leh ee CsxWO3

Sanduuqa dahaarka wuxuu ka samaysan yahay looxa xumbo.Meesha gudaha ee sanduuqa dahaarka waa 10cm*5cm*10.5cm.Xagga sare ee sanduuqu wuxuu leeyahay daaqad leydi ah oo 10cm*5cm ah.Qeybta hoose ee sanduuqa waxaa lagu daboolay saxan madow oo bir ah, heerkulbeegguna wuxuu si adag ugu xiran yahay birta madow.Dusha sare ee looxa.Ku rid saxanka muraayadda ah ee lagu daboolay CsxWO3 ee daaqada kuleylka kuleylka leh ee xaddidan, si qaybta daboolan ay si buuxda u daboosho daaqada bannaanka, oo ku dheji nalka 250W infrared masaafo toosan oo 25cm ah daaqadda.Heerkulka sanduuqa wax lagu duubo wuu kala duwan yahay xidhiidhka ka dhexeeya wakhtiga soo-gaadhista ayaa isbeddela.Isticmaal qaab isku mid ah si aad u tijaabiso xaashida maran.Sida laga soo xigtay spectrum gudbinta CsxWO3 galaas dahaarka ah, CsxWO3 dahaarka leh content ceium kala duwan waxay leedahay gudbin sare oo iftiin muuqda iyo gudbin hoose ee iftiinka infrared dhow (800-1100nm).Isbeddelka gaashaandhigga NIR wuxuu kordhiyaa kororka maadada ceiumka.Waxaa ka mid ah, dhalada dahaarka leh ee Cs0.33WO3 ayaa leh habka ugu wanaagsan ee gaashaanka NIR.Gudbinta ugu sareysa ee gobolka iftiinka muuqda ayaa la barbardhigay gudbinta 1100nm ee gobolka infrared ee u dhow.Gudbinta degmada ayaa hoos u dhacday ilaa 12%.

Saamaynta kuleylka kuleylka ee muraayadda daboolan ee CsxWO3

Marka loo eego natiijooyinka tijaabada ah, waxaa jira farqi weyn oo u dhexeeya heerka kuleylka ka hor CsxWO3 dhalada dahaarka leh oo leh waxyaabo kala duwan oo ceium ah iyo muraayadda aan la daboolin ee bannaan.Heerka kululaynta sixirka ee filimka daahan ee CsxWO3 ee ka kooban ceesium kala duwan ayaa aad uga hooseeya kan galaaska bannaan.Filimada CsxWO3 oo leh maadooyin kala duwan oo cesium ah ayaa leh saameyn kuleyl ah oo wanaagsan, saameynta kuleylka kuleylka ee filimka CsxWO3 waxay kordhisaa kororka maadada cesium.Waxaa ka mid ah, filimka Cs0.33WO3 wuxuu leeyahay saameynta kuleylka kuleylka ugu fiican, iyo farqiga heerkulka kuleylka kuleylka wuxuu gaari karaa 13.5 ℃.Saamaynta kuleylka kuleylka ee filimka CsxWO3 wuxuu ka yimaadaa waxqabadka ilaalinta infrared-ku dhow (800-2500nm) ee CsxWO3.Guud ahaan, sida ugu wanagsan ee waxqabadka gaashaanka infrared-ku dhow, ayaa ka sii wanagsan wax qabadkeeda kuleylka kuleylka.
