AbstractTwo-source optical quenching spectroscopy demonstrates that the four site-selective Er3+ photoluminescence (PL) spectra observed in Er-implanted GaN contribute to the above-gap excited Er3+ PL spectrum, with relative efficiencies determined by the carrier capture cross sections and concentrations of the defects or traps which mediate the excitation of each Er site. The above-gap pumped PL spectrum is dominated by two of the trap-mediated Er3+ PL spectra, while the highest concentration Er site, which is efficiently pumped only by direct 4f absorption, contributes only weakly. These experiments indicate that the same defects and impurities are involved in the trapmediated processes responsible for both the above- and the below-gap excitations of the Er3+ PL.
