Energy-dependent Purcell factor computed for the geometry described in the inset for an oscillating dipole at a distance of 3.55 from each hBN layer. The Purcell factor is normalized by its value at 1,000 cm −1 to highlight its enhancement within hBN’s type II Reststrahlen band (orange-shaded region). The green-shaded region indicates the Reststrahlen band of SiO 2 .
