Abstract

Angular distribution of the photoluminescence from trivalent rare earth ions (Eu3+) embedded inside a magnesium silicate photonic crystal with an inverse opal structure is experimentally and theoretically studied. The emission at frequencies near the first stop-band of the photonic crystal is shown to exhibit strong angular modulation. The angle-dependent Eu3+ photoluminescence is numerically simulated by evaluating the fractional density of optical states in the photonic crystal, with diffuse scattering on structural imperfections taken into account. Experimental data for the emission properties of thin inverse opal films are shown to be in agreement with the simulation results.
