Engineering the optical properties of Cu doped CeO2 NCs for application in white LED

Influence of Fe and Cu Co-Doping on Structural, Magnetic and Electrochemical Properties of CeO2 Nanoparticles

“…In the last few decades, various models such as carrier-mediated exchange, donor-impurity-band exchange, the bound-magnetic-polaron model (BMP), etc. in DMSs, have been used to explain the FM behavior of the dilute magnetic semiconductors [6,[26][27][28][29][30]. Lately, Coey et al [28] proposed an FCE mechanism for 5a) also displays weak ferromagnetic (FM) ordering at room temperature (RT), with small values of parameters such as the coercive field (H C = 32 Oe), remanence magnetization (M R = 1.1 × 10 −4 emu/g), and saturation magnetization (M S = 1.9 × 10 −3 emu/g).…”

Role of La substitution on structural, optical, and multiferroic properties of BiFeO3 nanoparticles

“…Hence, the direct bandgap energy was calculated by plotting the (αhv) 2 (y-axis) against hv (x-axis), using Schuster-Kubelka-Munk absorption function as shown in Fig. 3b-e (Channei et al 2014;Ranjith et al 2014;Kumari et al 2020). An intercept on the x-axis is obtained by extrapolating the linear region of (αhv) 2 vs. hv.…”

Effect of Europium, Yttrium and Lutetium Doping on the Photocatalytic Property of CeO2 Nanoparticles in the Reduction of p‐nitrophenol under Visible Light

“…Nanostructures of ceria (CeO 2 ) has been extensively explored due to its numerous applications in fields like catalyst, [3–5] sensor, [6–8] optical devices, [9,10] polishing materials, [11] diesel fuel additive, [12,13] photocatalyst, [14–16] and energy related applications [17] etc. So, it has extensively grabbed the interest of the scientists and has been synthesized in many ways using different physical and chemical methods like ball milling, [18,19] sol‐gel, [20–22] hydrothermal, [23–27] chemical precipitation, [28–32] microemulsion [33–35] and polyol methods [36–38] etc.…”
