Cesium Tungsten Bronzes(Cs0.32WO3) Assay Min.99.5% Cas 189619-69-0
Cesium Tungsten Bronzes(Cs0.32WO3) ndi chinthu chapafupi cha infrared chotengera nano chokhala ndi tinthu tating'ono komanso kubalalika kwabwino.Cs0.32WO3ili ndi chitetezo chabwino kwambiri chapafupi ndi infrared komanso mawonekedwe apamwamba owunikira. Imayamwa mwamphamvu m'dera lapafupi ndi infrared (wavelength 800-1200nm) komanso kufalikira kwakukulu kudera lowala lowoneka (wavelength 380-780nm). Tili ndi kaphatikizidwe bwino kwambiri crystalline ndi mkulu chiyero Cs0.32WO3 nanoparticles kudzera kutsitsi pyrolysis njira. Pogwiritsa ntchito sodium tungstate ndi cesium carbonate monga zopangira, cesium tungsten bronze (CsxWO3) ufa adapangidwa ndi kutentha kochepa kwa hydrothermal reaction ndi citric acid monga kuchepetsa.
