    Abstract: This paper reports the effect of temperature on the properties of TiO_2 nanomaterials, synthesis and characterization. TiO2 powders were synthesized by sol-gel method using TiCl4 solution added in deionized water in ice bath under fume hood followed by the addition of ethanol with vigorous stirring for 30 min at room temperature. The gel solution w... Show More

    Abstract: Silicon nanocrystals (Si-NCs) embedded in a Lanthanum Fluoride (LaF3) insulating layer were fabricated as a charge trapping layer by a simple Chemical Bath Deposition (CBD) technique. The X-Ray diffraction of the deposited layer shows a polycrystalline LaF3 deposition on silicon. The charge storage behavior of Si-NCs embedded in the LaF3 layer have... Show More

    Abstract: This study has investigated the effect of dopant concentration on the luminescent emission of Er3+ in ZrO2 nanocrystals. The structure and morphology of the resulting nanocrystals were characterized by X-ray diffraction and field emission scanning electron microscope. The room-temperature optical properties of synthesized nanocrystals were studied ... Show More
