Highly transparent and luminescent CaMoO4:Eu/Ag composite films were fabricated on glass substrates as multifunctional antireflective (AR) coatings. The films were deposited through a combination of a sol–gel dip-coating technique and a hot water treatment. With the addition of an aluminum source in coating solutions, the sol–gel-derived films underwent a remarkable microstructural change durin...

A two-step procedure was implemented to obtain tungsten oxide nanowires (WO3) doped with cobalt or silver oxide nanoparticles from metal-organic precursors, W(CO)6, Co(acac)2 and Ag(acac)2. In the first step, nanowires were grown at 400 °C using an aerosol assisted chemical vapor deposition system (AA-CVD) and subsequently annealed at 500 °C for 2 h. In the second step, metal loading (at differ...

Excitation of Xe monolayers on alumina-supported silver nanoparticles (AgNPs) by laser light in the (1,0) Mie plasmon resonance can lead to desorption of Xe atoms with hyperthermal energy and chaotic time structure. The chaotic behavior is most likely due to plasmonic coupling between AgNPs. We argue that the desorption is induced by direct energy transfer to the adsorbate from the Pauli repuls...

Abstract Current binary nanofluid synthesis methods with heat transfer additives lack an understanding of the chemistry nanoparticle-additive-base fluid interaction, which plays a significant role in adsorption surfactant on nanoparticle surface. Consequently, this leads to formation aggregates within after couple days, affecting stability colloidal suspension. Here, lithium bromide-alumina sal...

The matrix assisted pulsed laser evaporation (MAPLE) technique has been used for the deposition of metal dioxide (TiO(2), SnO(2)) nanoparticle thin films for gas sensor applications. For this purpose, colloidal metal dioxide nanoparticles were diluted in volatile solvents, the solution was frozen at the liquid nitrogen temperature and irradiated with a pulsed excimer laser. The dioxide nanopart...
