Studies on the simplified SILAR deposited magnetite (Fe3O4) thin films annealed at different temperatures

Copper and iron co-doping effects on the structure, optical energy band gap, and catalytic behaviour of Co3O4 nanocrystals towards low-temperature total oxidation of toluene

“…These observations are in good agreement with the literature. 50 The obtained absorption spectra were used to estimate the bandgap energies from Tauc's equation, and corresponding Tauc plot obtained from (ahu) 2 vs. hu is presented in Fig. 6b, d towards a lower value.…”

SILAR Deposition of Metal Oxide Nanostructured Films

“…have been reported for other materials including CdO (Figure 12c,d), [155,214,215] NiO, [167] CuO, [216] and Fe 3 O 4 . [217] Interestingly, NiO, CuO, and Fe 2 O 3 films have been prepared on glass substrates in three separate studies and were all subjected to the same thermal treatment at 200, 300, and 400 °C. In all these studies, despite being conducted independently and on different materials, a clear common trend in grain size (increasing with temperature) can be observed, however the bandgap energy is seen to vary depending of which material was studied (see Table 7).…”
