“…The line strengths are utilized to generate spectra as function of temperature and spectral resolution. Subsequently, these computed spectra are compared with experimentally measured data to infer, for example, micro-plasma characteristics and dynamics [22,[37][38][39]. Fig.…”

“…In general, tables of spectra that supply the full width at half maximum (FWHM) or the shift related to the electron density and temeperature and the plasma composition have been in use for this purpose (Parigger 2013). It is also frequently used and has proven to be particularly straightforward to use semiempirical or theoretically obtained data-fitting formulas, especially in research centers in which the plasma is not the main object but only a means.…”

Context. The Stark broadening of the spectral lines of the wavelengths 501. 6, 667.8, 728.1, 388.9, 587.6, and 706.5 nm from neutral helium in plasmas are studied theoretically and experimentally. Aims. The aim of this work is to provide information about the connection between the shape and width of spectral lines and the electron density and temperature to be used as a diagnostic tool. Methods. The theoretical calculations were carried out through molecular dynamics computer simulations with noninteracting particles. The experimental measurements were done in a plasma of pure helium generated in an electromagnetically driven T-tube. The plasma diagnostics used previous results about the Stark broadening of the He I 447.1 nm and He I 492.2 nm lines and the coherence between the shape of these spectra and those obtained here. The electron temperature was obtained through a Boltzmann-plot of eight lines of Si II. Results. Several tables of width and shift are provided in a wide range of electron density and temperature. Furthermore, we supply several fitting formulas, which allow calculating the plasma electron density from the measured values of the spectral line widths. The results obtained in the laboratory and in the simulations are compared with the data from the literature.

“…Presently two sources of band emission in LIP are known: plasma-induced luminescence (PIL) [10] and molecular emission [1][2][3][4][5][6]. Danburite and datolite are luminescent minerals with trivalent rare-earth element (REE) luminescence centers, such as Sm 3+ , Eu 3+ , Dy 3+ and Tb 3+ [11].…”
