The samples, which exhibit an excellent crystalline quality and smooth interfaces, are found to show broad luminescence below the GaN-bandgap which shifts with increasing indium content to longer wavelength. At elevated indium content an additional broadening of the luminescence band has been observed. A comparison of the AlInN bandgap and the luminescence energies shows a pronounced stokes shift. XPS measurements reveal a staggered band lineup in Al<sub>1-x<\/sub>In<sub>x<\/sub>N \/GaN heterostructures with x &gt; 0.25 is found. These findings indicate an indirect transition from the AlInN conduction to the GaN valence band as origin of the luminescence behavior. (\u00a9 2009 WILEY-VCH Verlag GmbH &amp; Co.
