Initially SNT glasses were prepared using high pure chemicals namely TeO<jats:sub>2<\/jats:sub>, Nb<jats:sub>2<\/jats:sub>O<jats:sub>5<\/jats:sub>, Na<jats:sub>2<\/jats:sub>CO<jats:sub>3<\/jats:sub>, B<jats:sub>2<\/jats:sub>O<jats:sub>3<\/jats:sub>, and SiO<jats:sub>2<\/jats:sub>. DTA analysis was performed to identify the glass transition (<jats:italic>T<\/jats:italic><jats:sub>g<\/jats:sub>) and crystallization (<jats:italic>T<\/jats:italic><jats:sub>c<\/jats:sub>) temperatures. Following the data of DTA, the initial host glass was annealed at different temperatures (450, 550, and 650\u2009\u00b0C). From the XRD pattern, glass annealed at 650\u2009\u00b0C is taken to be optimized temperature for the formation of glass\u2010ceramics from the host glass. The glass\u2010ceramics thus formed were found to be translucent rather transparent. Similar procedure is followed to form Er<jats:sup>3+<\/jats:sup> single doped and Er<jats:sup>3+<\/jats:sup>, Yb<jats:sup>3+<\/jats:sup> co\u2010doped SNT glass\u2010ceramics. It was found that the crystallite size in the glass\u2010ceramics calculated from the Debye Scherrer's formula is around the nano scale. Optical absorption and Judd\u2013Ofelt (J\u2013O) calculations were done for the transparent glasses doped with the rare earths. Radiative properties were also estimated from the J\u2013O parameters. NIR emission spectra specifically observing the 1.5\u2009\u00b5m luminescence of Er<jats:sup>3+<\/jats:sup> ion in the doped glasses and glass\u2010ceramics were recorded. It was found that nano glass\u2010ceramics co\u2010doped with Er<jats:sup>3+<\/jats:sup> and Yb<jats:sup>3+<\/jats:sup> ions were of maximum efficiency compared to single Er<jats:sup>3+<\/jats:sup> doped SNT glass which could be used for fiber amplifiers in the NIR region.<\/jats:p>","DOI":"10.1002\/pssb.201200788","type":"journal-article","created":{"date-parts":[[2013,3,14]],"date-time":"2013-03-14T01:14:59Z","timestamp":1363223699000},"page":"837-842","source":"Crossref","is-referenced-by-count":7,"title":["Enhancement of infrared emission in Er<sup>3+<\/sup>, Yb<sup>3+<\/sup> co\u2010doped sodium niobium tellurite nano glass\u2010ceramics"],"prefix":"10.1002","volume":"250","author":[{"given":"J.
