“…The slight turbidity of the solution in this stage still exists due to the incomplete solubility of the Cd thiolate complexes [2][3][4][5][6]. The solution is put in an equipped three-necked flask apparatus ( see Scheme (1)) and is deaerated by using N 2 bubbling for about 30 min [4][5][6][7][8].…”

Seed-mediated growth, a straightforward technique with a low reaction temperature and low cost, was used to create multi-functional core/shell nanoparticles (CdTe@FeOOH). X-Ray Diffraction (XRD), High-resolution transmission electron microscopy (HTEM), Energy-dispersive x-ray (EDX), Fourier-transform infrared techniques (FT-IR), and Differential Thermal Analysis (DTA) were utilized to study the structure and composition of the as-prepared CdTe@FeOOH quantum dots (QDs). Photoluminescence (PL) properties of CdTe@FeOOH (Core/Shell) in an aqueous solution were studied by steady-state and time-resolved PL spectroscopy. The PL lifetime of CdTe@FeOOH QDs was reduced as a consequence of PL quenching. This results in the electron transfer mechanism being efficient, which reduces electron–hole recombination in the core–shell composite. The utilization of core–shell nanospheres of this nature presents numerous potentialities for applications in the field of photocatalysis.

Effect of carboxylic acid and cyanoacrylic acid as anchoring groups on Coumarin 6 dye for dye-sensitized solar cells: DFT and TD-DFT study

Starting with Coumarin-6 dye, two novel D-π-A organic dyes C6X and C6N have been designed by attaching carboxylic acid and cyanoacrylic acid groups as anchoring groups to Coumarn-6 dye, respectively, to understand their potential use in dye-sensitized solar cells (DSSCs). The electronic structure and photophysical and photovoltaic properties of the novel designed dyes were studied using density functional theory DFT and time-dependent density functional theory TD-DFT with the Becke3-Parameter-Lee–Yang–Parr (B3LYP) functional and the 6-31G (d, p) basis set. Optimized structure and electronic properties (highest occupied molecular orbital energy (EHOMO), lowest unoccupied molecular orbital (ELUMO), and energy difference (Eg) between HOMO and LUMO) were calculated showing that C6N has the smallest band gap with the larger absorption region. Density of states (DOS), molecular electrostatic potential (MEP), natural bond orbital (NBO) analysis, non-linear optical (NLO) properties, UV–vis spectra, as well as some crucial parameters affecting the photovoltaic performance of DSSCs, such as light-harvesting efficiency (LHE), electron injection driving force (ΔGinject), dye regeneration driving force(ΔGreg), and the excited state life time(τe), were calculated to study the effect of the anchoring group on the DSSC performance. Additionally, the adsorption of C6X and C6N dyes on the TiO2 anatase (101) surface and the mechanism of electron injection were also investigated using a dye–(TiO2)9 cluster model using TD-B3LYP calculation. The calculated adsorption energies of the dyes suggest a strong adsorption of dyes to a TiO2 surface. The results show that C6N may be theoretically a good candidate as sensitizer of DSSC application.

The modified aqueous co-precipitation approach was used to successfully manufacture magnesium dititanate (MgTi2O5) nanoparticles. Thermogravimetric analysis/differential scanning calorimetry (TG/DSC) was used to clearly reveal the thermal stability. Moreover, pseudobrookite structure, and surface morphology of MgTi2O5 nanoparticles were determined using X-ray diffraction (XRD), transmission electron microscope (TEM), and Fourier-transform infrared (FT-IR), and scanning electron microscope (SEM) techniques, respectively. The average size of the crystallites calculated by Scherer approach was compared to Williamson-Hall and TEM images results. The optical band gap of MgTi2O5 nanoparticles was found to be 3.81 eV for direct transitions. The effect of temperature on the conductivity of DC electricity was tested between the rages 303–503 K. The data on antibacterial activity showed that MgTi2O5 nanoparticles were antimicrobial and stopped the test microorganisms from growing. These findings revealed that MgTi2O5 will be extensively promising in environmental pollution control and antibacterial research.
