The optical characterization was carried out by means of temperature and excitation density-dependent steady state photoluminescence (PL) spectroscopy, supplemented by room temperature PL excitation (PLE) and PL lifetime (PLL) measurements. The as-grown and as-implanted samples were found to exhibit a single green emission band attributed to localized excitons in the QW, although the N implantation leads to a strong reduction of the PL intensity. The green band was found to be surprisingly stable on annealing up to 1400\u00b0C. A broad blue band dominates the low temperature PL after thermal annealing in both samples. This band is more intense for the implanted sample, suggesting that defects generated by N implantation, likely related to the diffusion\/segregation of indium (In), have been optically activated by the thermal treatment.<\/jats:p>","DOI":"10.1038\/srep09703","type":"journal-article","created":{"date-parts":[[2015,4,8]],"date-time":"2015-04-08T13:47:50Z","timestamp":1428500870000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Luminescence studies on green emitting InGaN\/GaN MQWs implanted with nitrogen"],"prefix":"10.1038","volume":"5","author":[{"given":"Marco A.","family":"Sousa","sequence":"first","affiliation":[]},{"given":"Teresa C.","family":"Esteves","sequence":"additional","affiliation":[]},{"given":"Nabiha Ben","family":"Sedrine","sequence":"additional","affiliation":[]},{"given":"Joana","family":"Rodrigues","sequence":"additional","affiliation":[]},{"given":"M\u00e1rcio B.","family":"Louren\u00e7o","sequence":"additional","affiliation":[]},{"given":"Andr\u00e9s","family":"Redondo-Cubero","sequence":"additional","affiliation":[]},{"given":"Eduardo","family":"Alves","sequence":"additional","affiliation":[]},{"given":"Kevin P.","family":"O'Donnell","sequence":"additional","affiliation":[]},{"given":"Michal","family":"Bockowski","sequence":"additional","affiliation":[]},{"given":"Christian","family":"Wetzel","sequence":"additional","affiliation":[]},{"given":"Maria R.","family":"Correia","sequence":"additional","affiliation":[]},{"given":"Katharina","family":"Lorenz","sequence":"additional","affiliation":[]},{"given":"Teresa","family":"Monteiro","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2015,4,8]]},"reference":[{"key":"BFsrep09703_CR1","doi-asserted-by":"publisher","first-page":"408","DOI":"10.1002\/lpor.201200025","volume":"7","author":"J Cho","year":"2013","unstructured":"Cho, J., Schubert, E.
