Abstract A perfect crystalline phases of cuprous oxide were synthesized using electrochemical method at different duration ( 15, 30 and 60 min). The deposited samples examined by XRD, SEM, UV–Vis absorption Mott-Schottky measurements. effect the deposition time on optical dielectric properties Cu 2 O was studied in detail. x-ray diffraction indicated increasing crystallinity crystallite size with time. SEM micrographs exhibited grains three-faced pyramid shape increased improvement...
Lithium doping improves CsPbBr 3 perovskites films by enhancing optical properties and reducing non-radiative recombination for enhanced stability performance of perovskite thin based optoelectronic devices.
This work targets to control the growth orientation of sol-gel-derived ZnO thin films in order allow different modes excitation (longitudinal and transverse) when targeted be used piezoelectric applications. For that, effect solvents stabilizer molar ratio on structural optical characteristics obtained is investigated by means X-ray diffraction (XRD), scanning electron microscopy (SEM), UV-Vis spectrophotometry. The XRD results show clearly that synthesized exhibit hexagonal wurtzite...
Abstract In this work, five phenanthroline derivatives substituted with different methyl groups have been selected to synthesize β‐diketonate‐based europium complexes check the influence of substitutions on degradation effect those in poly(methyl methacrylate) (PMMA) films. The photophysical properties Eu(III) complexes, including absorbance, excitation, and emission carefully investigated solution, solid‐state, doped PMMA film. all these states, exhibit an impressive red at 614 nm a high...
In this work, thin CdS films have been deposited using the chemical bath deposition technique (CBD). Different synthesis parameters, such as number of runs, time, and postannealing temperature, are studied optimized in order to avoid supersaturation phenomenon achieve a low-temperature growth. films, cubic structure, oriented along (111) direction with homogenous smooth surface, by CBD growth process without any annealing treatment. Based on set experimental observations, we show that...
In this work, we investigated the effect of deposition potential on morphological, structural, and optical properties Cu2O thin films prepared FTO-coated glass substrates. The potentials electrodeposition are -0.3V, -0.4V, -0.5V. were optimized by cyclic voltammetry experiment for a slow scan rate 20mV/s. It has been found that significant influence films. X-ray diffraction revealed all crystallized in cubic phase with preferential orientation (111). Scanning electron microscope (SEM) images...
Precursor inks development contributed significantly to rapid escalations in solar-to-electrical conversion efficiencies of peorvskite solar cell technology.
In order to enhance the efficiency of photovoltaic solar cells and overcome their limitations, a matching between spectrum semiconductor band gap is needed using luminescent materials. The following work present in this paper mainly based on adjustment cell bandgap by developing downconverting Down conversion process exploited modify due cooperative energy transfer Tb <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3+</sup> two Yb rare earth...
