Título: | Study of broadband near-infrared emission in Tm3+-Er 3+ codoped Teo2Wo3-PbO glasses |
Autor: | Balda, Rolindes CSIC ORCID; Fernández, Joaquín CSIC ORCID; Fernández Navarro, José María CSIC | Fecha de publicación: | 2009 | Editor: | Optical Society of America | Citación: | Optics Express 17: 8781- 8788 (2009) | Resumen: | In this work, we report the near-infrared emission properties of Tm 3+-Er3+ codoped tellurite TeO2-WO 3-PbO glasses under 794 nm excitation. A broad emission from 1350 to 1750 nm corresponding to the Tm3+ and Er3+ emissions is observed. The full width at half-maximum of this broadband increases with increasing [Tm]/[Er] concentration ratio up to a value of ∼ 160 nm. The energy transfer between Tm3+ and Er3+ ions is evidenced by both the temporal behavior of the near-infrared luminescence and the effect of Tm3+ codoping on the visible upconversion of Er3+ ions. ©2009 Optical Society of America. | URI: | http://hdl.handle.net/10261/54497 | DOI: | 10.1364/OE.17.008781 | Identificadores: | doi: 10.1364/OE.17.008781 issn: 1094-4087 |
