The total spontaneous emission rate of a quantum emitter in the presence of an infinite MoS2 monolayer is enhanced by several orders of magnitude, compared to its free-space value, due to the excitation of surface exciton polariton modes and lossy modes. The spectral and distance dependence of the spontaneous emission rate are analyzed and the lossy surface wave, surface exciton polariton mode ...

The distinguishing features of the new type of unheated liquid metal field emitter are reported. The emitter is based on track membrane technology and therefore its surface cam be made as large as necessary. It is cheap in construction, fabrication and exploitation. The emitter can be operated indefinitely long time in field emission, explosive emission or ion emission mode by poor vacuum up to...

1 During the last decade, there have been excellent and very rapid advances in “Nuclear Medicine and Molecular Imaging” throughout the world. The developments in radiopharmaceuticals induced evolution of nuclear medicine from imaging certain biologic features to targeted drug delivery designed for the specific characteristics of an individual patient’s disease. While the use of therapeutic radi...

PURPOSE The ability of antibodies (Abs) conjugated to radionuclides emitting low-energy electrons to specifically kill nonadherent lymphoma target cells in vitro was demonstrated previously. This study extends this work to adherent carcinoma cells. The fact that these cells are spread out on plastic can potentially make it more difficult to deliver radiation to the nucleus from decays in the cy...

The geometry and dimension of a gold nanorod (GNR) are optimally designed to enhance the fluorescence intensity of a lanthanide-doped upconversion nanocrystal placed in close proximity to the GNR. A systematic study of the electromagnetic interaction between the upconversion emitter of three energy levels and the GNR shows that the enhancement effect arising from localized electric field-induce...

Proton decay has been transformed in recent years from an exotic phenomenon into a powerful spectroscopic tool. The frontiers of experimental and theoretical proton-decay studies will be reviewed. Different aspects of proton decay will be illustrated with recent results on the deformed proton emitter 135Tb, the odd–odd deformed proton emitter 130Eu, the complex fine structure in the odd–odd 146...

In this work we focus on the emitter formation and its dopant source, the PhosphoSilicate Glass (PSG), formed by POCl3 diffusion. An optimum emitter requires an exact adjustment of diffusion parameters, such as process temperature, time, POCl3-N2 gas flow and O2 gas flow. Another important process parameter which is normally kept constant but also has a strong influence on PSG and emitter forma...

Understanding the formation and spatial-temporal distribution of soil salt crusts (SSCs) is important for the sustainable management of the artificial shelterbelt and high-salinity groundwater utility in the Taklimakan Desert in Northwest China. The SSCs in this area were sampled, and their thickness and electrical conductivity (EC) were analyzed to examine the formation mechanism and the spati...

We study the angular emission of a single emitter near a metallic nanoparticle by experiments and numerical calculations. In the experiments, a single fluorescent molecule is controllably scanned near an optical monopole antenna. Large changes in the angular emission of the molecule occur due to the coupling to the particle. Both the polarization and intensity of the angular emission show a dis...
