These data are combined with structural data to determine the compositional dependence of emission and absorption energies. The trend indicates a very large bowing parameter of \u22486eV and differences with earlier reports are discussed. Very large Stokes\u2019 shifts of 0.4\u20130.8eV are observed in the composition range 0.13&amp;lt;x&amp;lt;0.24, increasing approximately linearly with InN fraction despite the change of sign of the piezoelectric field.<\/jats:p>","DOI":"10.1063\/1.2898533","type":"journal-article","created":{"date-parts":[[2008,4,7]],"date-time":"2008-04-07T17:43:21Z","timestamp":1207590201000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":59,"title":["Optical energies of AlInN epilayers"],"prefix":"10.1063","volume":"103","author":[{"given":"K.","family":"Wang","sequence":"first","affiliation":[{"name":"University of Strathclyde 1 Department of Physics, SUPA, , Glasgow G4 0NG, United Kingdom"}]},{"given":"R.
