Ultraviolet detectors based on annealed zinc oxide thin films: epitaxial growth and physical characterizations
In this report, ultraviolet (UV) detectors were fabricated based on zinc oxide thin films. The epitaxial growth of zinc oxide thin films was carried out on bare glass substrate with preferred orientation to (002) plane of wurtzite structure through radio frequency sputtering technique. The structural properties indicated a dominant peak at 2θ=34.28º which was matched with JCPDS reference card N...
متن کاملElectronic and Mechanical Properties of Ge Films Grown on Glass Substrates
As germanium is closed lattice matched to GaAs, it a suitable substrate for epitaxial growth. In the quest for inexpensive substrates, thin-film Ge grown on glass is an attractive candidate if suitable grain growth can be achieved. Here we will describe Ge films that are deposited by an e-beam evaporator on glass and are approximately 2000 Å thick. The films were annealed at 500 ̊ C and 600 ̊ C t...
متن کاملFabrication of Nb/V co-doped TiO2 thin films and study of structural, optical and photocatalytic properties
In this study, different samples of Niobium and Vanadium co-doped titania thin films (5-10-15 mol% Nb and 5-10-15 mol% V) were prepared via sol−gel dip coating method, using niobium chloride as niobium precursor, ammonium metavanadate as vanadium precursor, and titanium (IV) butoxide (TBT) as titanium precursor. The effects of doping amount on the structural, optical, and photo-catalytic prope...

متن کاملYb 3 + codoped NaMnF 3 nanocubes with single - band red upconversion luminescence †
Wehave developed a facile low-temperature synthetic method for the preparation of NaMnF3 nanocubes with Er 3+ and Yb ions homogeneously incorporated in the host lattice. The effects of the reaction temperature, and the volume ratio between ethanol and DI water on themorphology of NaMnF3 nanocubes are systematically investigated. The NaMnF3 nanocubes can be produced in the low temperature range ...
