“…This high intensity was observed due to the recombination of photoexcited carriers inside the nanocrystallites. [ 23 ] Besides this, the porosity values determine the change direction: lower porosity layers show redshift, while a blue shift is observed in higher porosity samples. [ 24 ] Thus, more annealed temperature helps to oxidize the CaFe 2 O 4 infiltration does not cause PL spectral change, suggesting a slight porosity adjustment.…”

In this work, CaFe2O4 is successfully synthesized with a natural source of precursors by the milling method. The X‐ray diffraction confirms the orthorhombic CaFe2O4 compound. Scanning electron microscopy shows agglomerated porous crystalline type morphology. Photoluminescence spectra show that CaFe2O4 absorbs visible regain at wavelength 584 nm. The synthesized CaFe2O4 compound shows p‐type gas sensing behavior and high gas response towards ethanol 38.4% at 225˚C operating temperature at a concentration of 120 ppm ethanol gas.

“…They show enormous applications in catalysis, drug delivery, toxicological, sensors, and photocatalysis. [1][2][3][4][5] These materials have superior chemical stability and thus are often used in place of sulfide materials. [6,7] Among oxide materials, spinels are one of the good host materials for low voltage cathodoluminesce (CL) phosphor, microwave absorption property, thin film electroluminescent displays, gas sensing, and vacuum fluorescent display (VFD).…”

Manganese and iron doped cadmium gallate has been synthesized by sol–gel approach. PXRD pattern shows the cubic arrangement of cadmium gallate spinel. Raman spectrum concludes the complete structural analysis of undoped and doped samples. Additionally, morphology and elemental ratio is obtained using FESEM and EDS spectroscopy. Blue indigo and green emission bands are shown in photoluminescence spectra. An excellent antiferromagnetic and ferromagnetic behavior of manganese and iron doped cadmium gallate are shown in the magnetic study. Low band gap of doped samples has made this material as a prominent catalyst for the degradation of methylene blue dye when exposed to UV–visible irradiation.

“…properties of ZnO thin lms [9]. In production of ZnO thin lms, there are a lot of obtained methods such as evaporation [10], sputtering [11], pulsed laser deposition [12], sol-gel [13] and chemical bath deposition [14]. Among these methods, the most preferred one is sol-gel which has simple stages of (i) exhausting, (ii) excess deposit processing, and (iii) drying, provides good control over the chemical composition with low temperature, low cost and low energy consumption [15].…”

Novel perimidine ruthenium complexes ([Ru(L1-2)(p-cymene)Cl]Cl) were synthesized and these synthesized Ruthenium (Ru) complexes were added to ZnO at content of 2, 4, 6 wt.% to fabricate Rudoped ZnO thin lms by the sol-gel spin-coating method. These lms were characterized using XRD, SEM, FT-IR, UV-Vis, and Photoluminescence (PL) spectra. All of the lms possessed a hexagonal wurtzite structure, according to XRD data. The observed stress was compressive, except for the A4 sample, and ranged from 0.21 GPa to 2.117 GPa as the ruthenium content increased from 0-6%. Residual stress values of Ru-doped ZnO thin lms showed a lower value than pure ZnO lm. It was obtained that the crystalline quality tended to improve as well as lower residual stress with increasing Ru amount. In the visible range, all the lms exhibited approximately transmittance greater than 70%. Further, the optical bandgap was 3.20 eV for pure ZnO and all Ru-doped lms' bandgap had between 2.76 and 3.18 eV. This research shows that new high conjugated structures are promising as dopant materials for the ZnO thin lm, and good crystalline and optical properties could be obtained from the Ru doped ZnO lms prepared by sol-gel for nano-optoelectronic devices.
