Considering it with the variation of the exited state life time, we could draw a conclusion that in the range of 77 K to 300 K, the influence of temperature on the emission cross section of Cr 4+ is re.

Information of the erbium--doped fiber s absorption and emission cross sections is very important for theoretical analysis and optimum design of erbium-doped fiber amplifiers.

Inner shell dielectronic recombination cross section excitation of Na like Ar 7+ ion is calculated.

Theoretical study on radiative recombination and subsequent radiative decay of H-like uranium ions

A detailed investigation was carried out of radiative recombination in n-GaAs homojunction far-infrared detector structures by temperature-dependent steady-state photoluminescence measurements.

The results show that the PL spectra of the epilayers with high radiative recombination efficiencies are basically composed of sharp lines due to recombination of excitons bound to the N, and NN i traps, whereas the PL spectra of the epilayers with low efficiencies are bell shaped spectra of donor acceptor pair transitions superimposed with the NN i peaks.

Bremsstrahlung and compound radiation of electron were considered as main mechanism of continuum emission.
