Título: | A borane laser |
Autor: | Cerdán, L. CSIC ORCID; Braborec, J.; Garcia-Moreno, I. CSIC ORCID; Costela González, Ángel CSIC ORCID; Londesborough, M.G.S. | Fecha de publicación: | 2015 | Editor: | Nature Publishing Group | Citación: | Nature Communications 6 (2015) | Resumen: | © 2015 Macmillan Publishers Limited. Emission from electronically excited species forms the basis for an important class of light sources-lasers. So far, commercially available solution-processed blue-emitting laser materials are based on organic compounds or semiconductor nanocrystals that have significant limitations: either low solubility, low chemical-and/or photo-stability and/or uncompetitive prices. Here we report a novel and competitive alternative to these existing laser materials that is based on boron hydrides, inorganic cluster compounds with a rich and diverse chemistry. We demonstrate that solutions of the borane anti-B 18 H 22 show, under pulsed excitation, blue laser emission at 406 nm with an efficiency (ratio of output/input energies) of 9.5%, and a photostability superior to many of the commercially available state-of-the-art blue laser dyes. This demonstration opens the doors for the development of a whole new class of laser materials based on a previously untapped resource for laser technology-the boranes. | URI: | http://hdl.handle.net/10261/130472 | DOI: | 10.1038/ncomms6958 | Identificadores: | doi: 10.1038/ncomms6958 issn: 2041-1723 |
