Simple Solvothermal Approach to Highly Nanostructured Hematite Thin Films [PDF]
, 2020 In this work, we present a solvothermal method for the synthesis of hematite thin films on fluorine-doped tin oxidesubstrates. This simple method uses a precursor solution of iron(III) 2,4-pentanedionate dissolved in ethanol with amicroliter-scale amount
