Thermoluminescence (TL) properties of Eu incorporated with CaBO phosphors prepared by solution-combustion process.

The solution-combustion approach was used to create CaBO:Euphosphors using Ba (NO), Eu (NO)·5HO, HBO, NH(ON)H, and NHNO as source materials. We investigated the thermoluminescence (TL) characteristics of beta (β)-irradiated CaBO:Eu. When the TL intensity was evaluated at different dosages of β, it rose with the dose.

Green Synthesis of Nickel Oxide NPs Incorporating Carbon Dots for Antimicrobial Activities.

A biosynthesis composite using the green synthesis of titled metal nanoparticles (nickel oxide nanoparticles, NiO NPs, and carbon dots, C-dots) was produced, characterized, and then applied for antimicrobial activities. NiO NPs were produced using the () plant leaf extract and nickel nitrate (III) hexahydrate [Ni(NO)·2HO] as precursors, while C-dots were produced using citric acid and -phenylenediamine (-OPD). The distribution of the average particle size of the NiO NPs and NiO NPs@C-dots was 25.

Modification of Flexible Electrodes for P-Type (Nickel Oxide) Dye-Sensitized Solar Cell Performance Based on the Cellulose Nanofiber Film.

The preparation of flexible electrode, including working electrode (WE) and counter electrode (CE), for dye-sensitized solar cells (DSSCs) utilizing metal oxides using environmentally friendly sustainable TEMPO-oxidized cellulose nanofibers (TOCNFs) is reported in this work. A new type of flexible electrode for the DSSCs, which were made of cellulose nanofiber composites with nickel hydroxide [CNF/Ni(OH)] substrate films and cellulose nanofiber composites with polypyrrole (CNF/PPY). Nickel hydroxide, Ni(OH), has been prepared hydrothermally in the presence of TOCNFs, [TOCNF@Ni(OH)].

Sol-gel produced ZnVO phosphors' improved luminous properties: The role of thermal treatment.

ZnVO phosphor was made using a sol-gel technique and then annealed at temperatures ranging from 700 to 850 °C. The x-ray diffraction (XRD) results revealed that ZnVO exhibits a single monoclinic phase. The width at half-maximum of the (022) XRD peak shrank overall resulting in improved crystallinity of the ZnVO phosphors with higher annealing temperatures.

Hybridization of nickel oxide nanoparticles with carbon dots and its application for antibacterial activities.

A nickel oxide nanoparticle (NiO NP) composite with carbon dots (C-dots), (NiO NPs@C-dots) was synthesized, characterized, and then its antibacterial activity was evaluated. NiO NPs were prepared using Buddleja polystachya Fresen leaf extract and Ni(NO ) .6H O as precursors.
