Solvothermal synthesis of Fe doped MnSnO ₃ : An approach of wide bandgap perovskite towards optical, luminescence, and electrochemical properties

Abstract

The present article investigates the fabrication of MnSnO 3, and Fe doped MnSnO 3 perovskite. We are reporting for the first time Fe doping perovskite material. The synthesis has been carried out under subcritical conditions. The optical, electrochemical, and luminescence properties were investigated. The structural determination of nanostructures has been carried out through XRD and Fourier transform infrared (FTIR). Furthermore, scanning electron micro-

“…9(a) shows the bandgaps of ANiO 3 (O- Pnma ) (A = Eu, Gd, Tb, Dy, Yb, La, Tm, Nd, Sm), EuBO 3 (O- Pbnm ) (B = Zr, Hf), EuTiO 3 (C- Pm 3̄ m ), DNbO 3 (O- Pnma ) (D = Ag, Ba, Ca, Sr, Eu, K, Na), SrTM 1 O 3 (C- Pm 3̄ m ) (TM 1 = Hf, Zr, Ti), KTaO 3 (C- Pm 3̄ m ), LaTM 2 O 3 (O- Pnma ) (TM 2 = Al, Sc, Fe, Cr, Ti, Ga, Co), SrTcO 3 (O- Pnma ), NaOsO 3 (O- Pbca ), MSnO 3 (R- R 3 c ) (M = Hg, Mg, Zn, Fe, Mn), NiSnO 3 (C- Pm 3̄ m ), SrNiO 3 (C- Pm 3̄ m ), BaSnO 3 (C- Pm 3̄ m ), CaSnO 3 (O- Pnma ), CoSnO 3 (O- Pnma ), TiSnO 3 (T- I 4/ mcm ), MnTiO 3 (R- R 3 c ), PbTiO 3 (T- I 4/ mcm ), CaZrO 3 (O- Pnma ), and BaFeO 3 (C- Pm 3̄ m ). As can be seen, there is good agreement in the bandgaps between our calculations and the experimental data and other reported HSE06 and G 0 W 0 data, 31–52 which demonstrates the accuracy of our method.…”

Bandgap Engineering through Fe Doping in Cs2SnCl6 Perovskite: Photoluminescence Characteristics and Electronic Structure Insights

“…These disruptions can manifest as structural defects, distortions, or even the formation of secondary phases. As a consequence of these disturbances, the XRD peaks experience a shift toward lower 2θ values, contrary to the anticipated higher angle shift. − The incorporation of Fe in place of Sn in the Cs 2 SnCl 6 perovskite can lead to significant effects on lattice parameters and induce structural changes in the crystal lattice. These changes are associated with the differences in ionic radii and chemical properties between Sn and Fe.…”

“…Figure 12A shows the CV curves for MnTiO 3 at different scan rates (10-35 mV s À1 ) in the potential range of À0.2 to 0.4 V. The shape of the voltammograms obtained resembles almost a rectangular shape depicting utility of MnTiO 3 in supercapacitors. The specific capacitance of the material was calculated by the following equation 35 :…”

“…Figure 12A shows the CV curves for MnTiO 3 at different scan rates (10‐35 mV s −1 ) in the potential range of −0.2 to 0.4 V. The shape of the voltammograms obtained resembles almost a rectangular shape depicting utility of MnTiO 3 in supercapacitors. The specific capacitance of the material was calculated by the following equation 35 : where C s is the specific capacitance (F g −1 ), A is area of the Voltammogram curve (m 2 ), m is mass (g) of the active material, k is the scan rate (V s −1 ) and (V2‐V1) is potential window (V). Abiding shapes of the CV curves with increase in scan rate represent the stability of MnTiO3.…”
