Spin coat thickness
WebJun 7, 2014 · The thickness of the deposited layers was determined after the spin-coating process and after the thermal decomposition at 500 °C. The longer polymer chain expectedly increases the viscosity of the precursor solution and produces thicker films by spin-coating. At this point, the thickness scales with µ 0.40 as PVP WebApr 12, 2024 · A 50 nm-thick compact TiO 2 (c-TiO 2) layer (250 µL) was deposited onto the FTO by the spin coating method previously reported by our group and for 30 min heated at 500 °C. A mesoporous TiO 2 layer was deposited on the c-TiO 2 by using a 1:6 w / w diluted paste (IRASOL) in ethanol (30 µL) via spin coating for 20 s at 4000 rpm and was ...
