Traditionally, it has been assumed that electroluminescence (EL) in time projection chambers was purely an excimer-based emission. This idea changed when neutral bremsstrahlung (NBrS) was observed first in argon and subsequently in xenon a few years ago. In this work we explore further the framework used to explain these observations, presenting results for noble gas -based mixtures, as well as mixtures including small fractions of a molecular additive (`quencher'). Spectral content and yields are discussed in some cases of contemporary interest, together with their pressure-scalings.
