Cesium Tungsten bronzes (CS0.32WO3) assay Min.99.5% CAS 189619-69-0
CESIES TUNGSTEN BRANZES(Cs0.32wo3) yog nyob ze-infrared absorbing nano cov khoom siv nrog cov khoom sib txawv thiab kev tawg ua kom zoo.Cs0.32wo3Muaj kev tiv thaiv zoo heev nyob ze ntawm kev tiv thaiv kev tiv thaiv kev ua yeeb yam thiab muaj kev hloov pauv lub teeb. Nws muaj kev nqus tau zoo nyob rau hauv thaj chaw ze-infrrared (wavelengthge 800-1200nm) thiab kev hloov pauv siab hauv cov cheeb tsam pom (nthwv dej 380-780nm). Peb muaj cov synthesis muaj kev vam meej ntawm cov crystalline thiab siab purity cs0.3 nanoparticles los ntawm tshuaj tsuag pyrolysis txoj kev. Siv sodium tungstate thiab cesium carbonate raws li cov ntaub ntawv raw, ciceeb tungsten los ntawm cov tshuaj tiv thaiv kub tsawg (citric acid raws li tus neeg sawv cev liab.
