Semiconductor nanocrystals (NCs) or quantum dots (QDs) show great promise for use in QD-LED (quantum dot lightemitting device) displays, owing to their unique optical properties and the continual development of new core and core–shell structures to meet specific color needs. This in combination with the recent development of more efficient and saturated QD-LEDs as well as new QD-LED fabrication...

Blue-light-emitting ZnSe core (C) and ZnSe/ZnS core/shell (C/S) quantum dots (QDs) were synthesized with phosphine-free precursors by a thermal decomposition method in paraffin oil solvent applied to QD-converted light-emitting diodes (LEDs). The optical properties of the C C/S QDs characterized absorption spectroscopy photoluminescence spectroscopy. Additionally, efficiency was investigated. T...

BACKGROUND We evaluated the Ziehl-Neelsen staining (ZNS) technique for the diagnosis of paragonimiasis in Laos and compared different modifications of the ZNS techniques. METHODOLOGY WE APPLIED THE FOLLOWING APPROACH: We (1) examined a paragonimiasis index case's sputum with wet film direct examination (WF) and ZNS; (2) re-examined stored ZNS slides from two provinces; (3) compared prospectiv...

The effects of ZnS/Metal/ZnS multilayer anodes, including ZnS/Au/ZnS (ZAuZ), ZnS/Ag/ZnS (ZAgZ) and ZnS/Cu/ZnS (ZCuZ) on device performance in organic light emitting diodes based on rubrene were investigated systematically. The device with ZAuZ as anode gave an improved performance comparable with ITO based devices. A low driving voltage of 5.61 V and a high luminance of 1836 cd/m were obtained ...

Ambidextrous magnetic circularly polarized luminescence (MCPL) is observed for the first time from five kinds of achiral soluble diamagnetic CdS/ZnS core-shell quantum dots in toluene and aqueous solutions, dispersed poly(methyl methacrylate) film, as solid powders when subjected to external north-up south-up fields 1.6 Tesla. The magnitude MCPL, gMCPL, on order |gMCPL| = 10–3 between 400 460 n...

We report a highly bright and stable aqueous dispersion of CuInS2/ZnS (CIS/ZnS) nanocrystals (NCs) using surfactant-assisted microemulsion and cold treatment. CIS/ZnS NCs were facilely synthesized via a stepwise, consecutive hybrid flow reactor approach. To stabilize the optical properties of hydrophobic CIS/ZnS NCs, cetyltrimethylammonium bromide (CTAB) was chosen as a matrix for aqueous phase...
