Using energy-momentum spectroscopy, we experimentally show that the near-infrared 3T2→3A2 emission from divalent-nickel-doped magnesium oxide (Ni2+:MgO) is composed of ∼50% MD and ∼50% ED transitions. We then demonstrate that the spontaneous emission rate of these ions near planar interfaces is determined by the combined electric and magnetic local density of optical states (LDOS). This electromagnetic LDOS probes the total mode density, and thus similar to thermal emission, these unique electronic emitters effectively excite all polarizations and orientations of the electromagnetic field.
