In this study, methyl ammonium lead Iodide perovskite (CH3NH3PbI3≡MAPbI3) was deposited as a thin planar film on a glass substrate at room temperature using one-step and two-step methods. The effect of each method of preparation on the structural,...
Cesium lead bromide (CsPbBr3) perovskite has recently gained significance owing to its rapidly increasing performance when used for light-emitting devices. In this study, we used density functional theory to determine the structural, electronic, and...
The structural, electronic, and optical features of CsPb(I1-xBrx)3 (x = 0, 0.25, 0.50, 0.75, and 1.0) compounds were evaluated using first-principles calculations based on the full-potential linear augmented plane wave (FP-LAPW). The ground-state...
Composite materials with different concentration ratios of a hybrid of zero-dimensional (0-D) Cs4PbBr6 perovskite, which acts as a donor (D), and poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV), which acts as an acceptor (A),...
The aim of this study is to investigate the optical and structural properties of polymer/perovskite quantum dots (QDs) composite thin films and estimate the applicability of using these blends as active materials in photonic devices. A solution has...
Brookite TiO2 is the most difficult synthesized TiO2 polymorph. The available methods in the literature to produce brookite nanostructures mostly use water-based techniques for the preparation of water-soluble Ti complexes first, followed by a...
Photophysical and energy transfer mechanism of the Poly (9,9-di-n-octylflourenyl-2,7-diyl) (PFO)/Fluorol 7GA (F7GA)/Poly [2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV) blend thin films were investigated for potential applications as...
Different weight ratios of poly(9,9-dioctyl-fluorene-2,7-diyl) (PFO)/poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV) hybrid thin films, with and without a SiO2/TiO2 nanocomposite (NC), were successfully prepared using a solution...
In this paper, titanium dioxide (TiO2) thin films, deposited on single crystal Si (111) substrates under different temperature conditions by Atomic Layer Deposition (ALD), have been systematically studied by X-ray diffraction, photoluminescence ...
The authors report amplified spontaneous emission (ASE) behaviour from methylammonium lead iodide (CH3NH3PbI3) perovskite films of different thicknesses. The ASE threshold carrier density noticeably decreased with thickness, indicating the existence...
In this paper, we present a study of the structural and optical properties of organic–inorganic halide-based perovskite semiconductors with band gaps varying from NIR to visible at room temperature. Thin films of nanocrystalline CH3NH3PbI3 with...
Dye-sensitized solar cells (DSSCs) based on TiO2 nanoparticles and TiO2 nanosheets with exposed {001} facets are investigated using laser-induced photovoltage and photocurrenttransient decay (LIPVCD) measurements. We adopted a simplified version of...
Dye-sensitized solar cells (DSSCs) have been considered as one of the most promising new generation solar cells. Enormous research efforts have been invested to improve the efficiency of solar energy conversion which is determined by the light...
Nanostructured fluorescent pyrromethene (PM) doped-silica core-shell particles were successfully prepared by Stöber process. The average size of the particles was in the range of 10–20 nm measured by TEM micrograph. The atomic structure and...
Rhodamine (Rh6G) dye-silica core–shell nanoparticles (DSCSNPs) have been prepared by the controlled hydrolysis and condensation of single silica precursor tetraethylorthosilicate (TEOS) using the sol–gel method. Scanning electron microscopy,...
