“…The same trend has been reported by several authors [28]. In general, it is reported that introduction of doping atoms reduces the crystallite size regardless the host network such as ZnO, TiO 2 , SnO 2 [29] [30] [31]. This may originate from the early stage of nucleation during film growth, actually, any foreign atom acts as a nucleation center, therefore the nucleation centers is increased in doped films causing the reduction of crystallite size.…”

In the present work, undoped (SnO 2) and fluorine-doped tin oxide (FTO) thin films were prepared by sol-gel process using a solution composed of (SnCl 2 , H 2 O), (NH 4 F), and ethanol mixture. The fluorine concentration effect on structural, optical and electrical properties of SnO 2 films is investigated. The electrical properties of FTO films prepared by sol gel remain relatively lower than the ones deposited by other techniques. In present paper, we try to elucidate this difference. Films composition and the FTIR analysis, of films and formed precipitate during film growth, indicate that few amounts of fluorine are incorporated in SnO 2 network, most of fluorine atoms remain in the solution. The films resistivity is reduced from 1.1 Ω•cm for undoped films to 3 × 10 −2 Ω•cm for 50 wt.% doped FTO, but remains higher than the reported ones in the literature. This high resistivity is explained in terms of fluorine bonding affinity in the solution.

“…This increase in the λ max value accounts for shifts in the band gap towards lower energy after ZnO modification (Table S2). This decrease in the band gap is attributed to metal incorporation [41][42], and can be explained in terms of increase in the electron density around Fe o NPs, as already reported [43]. Plotting (αhν) 2 versus hν (Fig.…”

“…It is likely to be interpreted that the strong exchange interactions between d electron of Mn, with s and p electrons of host matrix causing some changes on the electrical and optical properties . The similar bandgap shrinkage induced by the addition of Mn ions was also found in ZnO and BiFeO 3 .

Optical properties of lead‐free ferroelectric pure and Mn‐doped 0.92Na0.5Bi0.5TiO3‐0.08K0.5Bi0.5TiO3 (NBT‐8KBT) single crystals have been investigated systematically. Refractive index and extinction coefficient were measured and the critical parameters are obtained by modified Sellmeier dispersion equations and single‐oscillator dispersion relation. The decline of refractive index for Mn:NBT‐8KBT could be related to the lattice distortion of the Mn ions doping. High transmittance (>70%) over the transparent region (>400 nm) was found in the pure NBT‐8KBT, higher than that of Mn:NBT‐8KBT, which could be caused by the increase of domain wall density. An about 100 nm red‐shift of absorption edge was observed in the Mn:NBT‐8KBT single crystal, which is located in the visible region. Optical bandgap energies calculated through Tauc equation and a large bandgap difference of 2.96 and 2.62 eV occurs in the NBT‐8KBT and Mn:NBT‐8KBT, respectively, which illustrates the modulation of the band structures by Mn doping.
