The In-rich Al1-xInxN films were grown on Si and quartz substrates by radio-frequency magnetron sputtering. The structures, morphologies, and optical bandgap of as-grown Al1-xInxN films were characterized by X-ray diffraction, scanning electron microscopy, and ultra-violate-visible-near infrared spectroscopy. The photoluminescence (PL) spectra of Al1-xInxN films were measured at room temperature. The Al1-xInxN films have single-phase wurtzite structures with (002) preferred orientation. The In content x was tuned in the range of 0.64-0.76. With increasing the In content x, the Al1-xInxN films exhibit smoother surface morphology and the optical bandgap shows a red-shifted from 1.93 eV to 1.87 eV. The PL emission is dominated by the band edge emission at x = 0.64. The additional emission could be explained by the Burstein-Moss effect when the In content x was increased.
