Growth Kinetics and Optical Properties of CsPbBr3 Perovskite Nanocrystals

“…Figure 3 shows Tauc plots for the CsPbBr 3 perovskite NCs prepared at different temperatures. The shape of the absorption edge in the absorption spectra of the CsPbBr 3 perovskite NCs is related to electronic transitions in the band-edge region [22]. The optical bandgap of the CsPbBr 3 perovskite NCs was calculated from the Tauc plots, which are valuable for determining the bandgap energy.…”

“…The optical bandgap of the CsPbBr 3 perovskite NCs was calculated from the Tauc plots, which are valuable for determining the bandgap energy. The absorption coefficient (α), which is directly proportional to the optical density and incident photon energy (hυ), can be used to determine the optical bandgap by extrapolating the straight-line portion of the plot of the quantity (αhυ) 2 vs. photon energy [22]. The authors of a previous study reported that the calculated bandgap of perovskite materials from the Tauc plot compares with the discrete Fourier transform computed bandgaps [23].…”

Linear and nonlinear optical properties of functionalized CdSe quantum dots prepared by plasma sputtering and wet chemistry

“…RFMS was previously successfully used for the deposition of TiO 2 , Ge, Si, ZnO, GaAs, CuInSe 2 and CdS QDs [13][14][15][16][17][18][19][20][21][22]. RFMS was also applied to the deposition of CdSe thin film and CdSe quantum dots embedded in SiO 2 or in an organic matrix [23,24]. However, to the best of our knowledge, there is no work devoted to the preparation of layers of clean CdSe QDs on a solid surface using RFMS.…”

The Synthesis and Properties of Cadmium Selenide Nanostructures

“…The devices were stored under atmospheric conditions between experiments. CdSe nanoparticles immersed in an organic matrix of amylopectin have been synthesized by means of the rf magnetron-sputtering growth technique by E. Campos-Gonzalez et al [11] . The target was elaborated employing a mixture of CdSe and amylopectin high purity powders.…”

“…Among them, hydrothermal or solvethermal method is regarded as a very effective and potential soft-chemistry route to tune the architectures of cadmium selenides. The great progress has been made in shape and size controlled growth of cadmium selenide [7][8][9][10][11][12][13][14] . In this paper, the synthesis of cadmium selenide is reviewed, with particular focus on the shape and size control.…”
