Rare-earth garnet selective emitter
Thin film (Ho)-yttrium aluminum garnet (YAG) and Er-YAG emitters with a platinum substrate exhibit high spectral emittance in the emission band (ελ≊0.75, 4I15/2–4I13/2, for Er-YAG and ελ≊0.65, 5I7–5I8 for Ho-YAG) at 1500 K. In addition, low out-of-band spectral emittance, ελ
