Description

Application

• The Effect of Precursor Concentration on the Particle Size, Crystal Size, and Optical Energy Gap of Ce(x)Sn(1-x)O(2) Nanofabrication: This study explores the role of precursor concentration, including Tin(II) chloride dihydrate, in the control of particle size and crystal size during the fabrication of cerium-doped tin oxide nanomaterials. These parameters critically influence the optical properties and energy gap of the produced nanomaterials, making the compound valuable in applications like sensors, catalysts, and energy devices (Al-Hada NM et al., 2021).
