Electroluminescence from Phosphor-doped nanocrystals
Alternating current thin-film electroluminescent (ACTFEL) devices already occupy a segment of the largearea, high-resolution, flat-panel-display market. The AC-TFEL displays, which consist of a phosphor layer, such as manganese doped-zinc sulfide (ZnS:Mn), vertically sandwiched between two insulators that are contacted by electrodes, are robust, possess long lifetimes, and offer high luminance ...
متن کاملAncient DNA from Salmon Bone: a Preliminary Study
INTRODUCTION In the Pacific Northwest of North America, archaeological saImonid remains have great potential to inform on issues of prehistoric cultural use, salmonid paleobiology and past environments. One hindrance to using prehistoric salmonid remains has been the gross level of taxonomic identification generally achieved. Species diagnostic elements are rarely found in archaeological contex...
متن کاملIdentification Caspian salmon Salmo caspius (Kessler, 1877) and rainbow trout Oncorhynchus mykiss (Walbaum, 1792) by extracting DNA from water (eDNA)
Proof of species existence in different regions can be useful for studying the migration pattern of the species. The use of non-invasive methods such as eDNA can be very effective in tracking and dispersing and improving the management of water resources and species. In this study, 15 water samples were taken from different areas of the southern Caspian Sea basin. Amino-modified silica-coate...
متن کاملElectroluminescence from a single-nanocrystal transistor.
We report the fabrication and characterization of light-emitting transistors incorporating individual cadmium selenide (CdSe) nanocrystals. Electrical measurements conducted at low bias voltage and low temperature show clear evidence of Coulomb blockade behavior, indicating that electrons pass through the nanocrystal by single-electron tunneling. Once the bias voltage exceeds the band gap of Cd...
متن کاملTerahertz electroluminescence from superlattice quantum cascade structures
Intersubband electroluminescence is reported in a quantum-cascade structure based on asymmetric superlattice active regions and designed for emission in the THz range ~l'80 mm!. Comparison with a structure based on a ‘‘vertical transition’’ in a single quantum well shows an increased full width at half maximum ~2.8 vs 0.9 meV! of the emission line. In both cases the dependence of the optical po...
