Manganese doped fluorescent paramagnetic nanocrystals for dual-modal imaging
In this work, dual-modal (fluorescence and magnetic resonance) imaging capabilities of water-soluble, low-toxicity, monodisperse Mn-doped ZnSe nanocrystals (NCs) with a size (6.5 nm) below the optimum kidney cutoff limit ...
Nonradiative energy transfer in a layered metal-dielectric nanostructure mediated by surface plasmons
Nonradiative energy transfer (NRET) has been applied in various applications of Nanosensors, Raman scattering, color tuning, light harvesting and organic light emitting structures. Due to the small range of donor-acceptor ...
Polarization-resolved plasmon-modulated emissions of quantum dots coupled to aluminum dimers with sub-20 nm gaps
An aluminum dimer nanoantenna with nanogaps is an ideal platform for enhancing light–matter interaction at the nanoscale for the UV–vis spectrum, but its realization has been hindered by the surface oxidation of aluminum ...
Exciton dynamics in colloidal quantum-dot leds under active device operations
Colloidal quantum-dot light-emitting diodes (QLEDs) are lucrative options for color-pure lighting sources. To achieve high-performance QLEDs, besides developing high-efficiency quantum dots (QDs), it is essential to ...
Improved performance of InGaN/GaN flip-chip light-emitting diodes through the use of robust Ni/Ag/TiW mirror contacts
In this work, the authors report the incorporation of TiW alloy in InGaN/GaN-based flip-chip light-emitting diodes (LEDs). The advantages provided by the use of TiW are analyzed in detail. InGaN/GaN multiple quantum well ...
