WO3 nanoparticles buluu ufa 99.9% kwa Electrochromic

Mafotokozedwe Akatundu

Electrochromism imatanthawuza chodabwitsa kuti mawonekedwe a kuwala (kuwonetsetsa, kufalikira, ndi kuyamwa) kwa zinthu kumasinthidwa ndikusintha mtundu wokhazikika pansi pa mphamvu ya magetsi akunja.Chifukwa zipangizo za electrochromic zili ndi ubwino wa magetsi otsika amtundu, kusintha kwa mitundu yosiyanasiyana, kupulumutsa mphamvu ndi kuteteza chilengedwe, zimagwiritsidwa ntchito kwambiri m'mawindo anzeru, magalasi owonetsera kumbuyo kwa galimoto, zipangizo zobisala, nsalu za electrochromic, kusunga zidziwitso ndi kuzindikira, zowonetsera, etc. Zoyembekeza za ntchito.
Tungsten trioxide ndi n-mtundu semiconductor chuma komanso mtundu wa "d0" okusayidi.Choyimira chachikulu cha tungsten oxide chimapangidwa ndi tungsten oxide octahedron olumikizidwa kumapeto mpaka kumapeto.Mu danga chimango, wazunguliridwa ndi tungsten okusayidi octahedra.Pores amatha kulowetsedwa m'magawo ang'onoang'ono kuti apange tungsten bronze.Kusintha kosinthika kwa tungsten oxide ndi tungsten bronze nthawi zonse kumatsagana ndi kusamutsidwa kwa ma elekitironi amkati ndikusintha kwa valence ya tungsten, komwe kumayambitsa mawonekedwe amtundu ndikuzindikira kusintha kosinthika kwa kuwala kofalikira.
Pakali pano, tungsten trioxide yokhala ndi electrochromic yabwino kwambiri ndi blue tungsten oxide.Tungsten oxide mu mtundu wachikuda ndi mdima wabuluu.Chifukwa cha mtundu wake wofewa komanso zotchinga bwino zotchinga kuwala, ndizoyenera kugwiritsidwa ntchito tsiku ndi tsiku.Kuphatikiza apo, crystalline blue tungsten oxide imakhalanso ndi mawonekedwe apamwamba ku infrared pambuyo pa kusinthika.Ikhoza kukwaniritsa kutentha kwa kutentha mofanana ndi magalasi otsika, potero kumathandiza kuchepetsa mphamvu ya m'nyumba.
Kuonjezera cesium ku tungsten oxide ndi chinthu chodziwika bwino chomwe chimapangidwa ndi chithunzi, komanso chimatchedwanso bronze wa cesium tungsten.Koma poyerekeza ndi tungsten oxide yoyera, mtengo wake ndi wapamwamba.

Nano-tungsten oxide ndiye chinthu chodziwika bwino cha zokutira zanzeru, ndipo ubwino wake ndi electrochromic.Kuphatikiza apo, tungsten trioxide imakhalanso ndi ntchito zosiyanasiyana mu gastrochromism, zosefera, komanso kukopa utoto.
