Sonication-Assisted Synthesis of -Mercuric Sulphide Nanoparticles
The nanoscale semiconductor β‐mercuric sulphide (HgS) has promising applications in electronic and optical fields. Continued development of synthesis methods is needed to expand approaches that produce uniform particles, while avoiding reagents of high toxicity and ecological impact. A solvent‐based approach was developed using mercuric chloride and elemental su...
متن کاملLocalizing of a Four-Level Atom via Absorption Spectrum
We propose a scheme for localizing an atom in a four-level configuration inside a classical standing wave field, conditioned upon the measurement of frequency of a weak probe field. In the classical standing wave field, the interaction between the atom and the field is position dependent due to the Rabi-frequency of the driving field. Hence, as the absorption frequency of the probe field is mea...
متن کاملControlling of Absorption and Dispersion Spectrum via Electromagnetically Induced Transparency
In this paper we examine the absorption and dispersion properties of a weak probe field via Electromagnetically Induced Transparency (EIT) in a four-level system. It is shown that under certain condition, using this model, the absorption cancellation is appeared and the medium becomes transparent to the weak probe field. It will be shown that the controlling of absorption and dispersion spectru...
متن کاملAbsorption and emission spectrum
It is well known that main group metal ions with an s* electron configuration form a large variety of polynuclear coordination compounds [l]. Recently it has been suggested that in these compounds a weak metal-metal bonding may exist which is achieved by sp orbital mixing [2]. In particular, calculations on Tl+ clusters were used to support this idea. Unfortunately, the metal-metal interaction ...
متن کاملA Preliminary Note on the Absorption of 'Makaradhwaja' (Sulphide of Mercury)
a great hold on the minds of the people in India that many practitioners of Western medicine also use it. There is probably something of real value about it, as it has resisted the ravages of time for many centuries and is universally esteemed to the present day. Preparation of ' makaradhwaja ?It is necessary at the outset to outline the process of preparation of this drug, as according to the ...
