Emission patternPhotons emitted from a single emitter are promising candidates for an efficient single-photon source, which is essential for many novel nano- and quantum-optical applications. As a photon source having a larger flux and high reliability is highly desirable. In this paper, we ...
Both are functions of the wavelength. This connection can be formalized by comparing the optical absorption process with the emission process and this can be done by using the principle of detailed balance. This equates the rate of disappearance by absorption of photons with the rate of ...
Altogether, the critical parameter for any source considered can be summarized as its "emission rate of hydrogen-ionizing photons per unit cosmological volume." 最後,來源的關鍵參數可被總結成「單位宇宙體積氫電離光子的發射率」。 LASER-wikipedia2 The differing emission rates of the various modes ...
It is known that surface plasmon mediated fluorescence comprises of excitation and emission enhancements. In particular, for emission enhancement, the energy from the excited emitters is first coupled to surface plasmon polaritons (SPPs), which in turn radiatively scatter to far-field. However, these...
The effect of generation rate on transient photoconductivity of semi-insulating (SI) 4H-SiC is discussed. The rate of generation of electron–hole pairs is dependent on the number of photons incident on the sample material and its absorption and reflecti
Figure 3.Transfection of B50 rat neuroblastoma cells with 10μg of plasmid DNA containing the firefly luciferase gene by electroporation using a CD pulse (τ = 2ms). Light emission was proportional to the expression of the luciferase gene. ...
X-radiation has a forward peaked emission and the rate at which a material receives X-radiation photons,thedose-rate,canbe controlled by a combination of the distance from the target, the beam current and under-beam transport speed. iba-asiapacific.com ...
. The average number of photons per pulse40for the linearly polarised fraction of the single photon emission at the first lens is calculated to be\(\left\langle n\right\rangle =(0.138\pm 0.015)\), taking into account the efficiencies of the transmitter and detector (see Table1). It is ...
(_2\)e for one liter of ECO2 and ECO3 is around 4.5 times lower than the CO\(_2\)e of one liter of STD mixture. Moreover, ECO2 and ECO3 mixtures feature similar values of CO\(_2\)e because most of it is due to the emission of SF\(_6\), which is quite similar in the ...
This universal detector generates a pulsed discharge in high-purity (≥6.0) He that leads to the emission of photons with an energy range of 13.5–17.7 eV. A small fraction of the analytes present in the carrier gas are ionized by these photons. The resulting free electrons are focussed ...
