Emission lines from Ne are frequently used as wavelength standards in spectroscopy. Reading around Wikipedia, I found about the Paschen law regarding the voltage required to start a discharge.
My question, do emission line intensities have dependence on the voltage applied and the temperature of the electrodes. Just to clarify, I am not thinking about the band positions but the relative intensities.
- About voltage dependence, at present I have no idea.
- About temperature : Since the electronic states are involved, and this is an electric discharge, the temperature maybe quite high so as to affect the Boltzmann population significantly.
This question is related to plasma physics, but also to electronic spectroscopy.
