High-pressure lattice dynamical study of bulk and nanocrystalline In2O3

Garcia Domene, Braulio; Ortiz, H. M.; Gomis Hilario, Oscar; Sans, J. A.; Manjón Herrera, Francisco Javier; Muñoz, A.; Rodríguez-Hernández, P.; Achary, S. N.; Errandonea, D.; Martínez-García, D.; Romero, A. H.; Singhal, A.; Tyagi, A. K. (American Institute of Physics (AIP), 2012-12-19)

The effect of pressure on the vibrational properties of bulk and nanocrystallinepowders of cubic bixbyite-type In2O3 has been investigated at room temperature by means of Raman spectroscopy up to 31.6 and 30¿GPa, respectively. ...
Highly fluorescent C-dots obtained by pyrolysis of quaternary ammonium ions trapped in all-silica ITQ-29 zeolite

García Baldoví, Hermenegildo; Valencia Valencia, Susana; Alvaro Rodríguez, Maria Mercedes; Abdullah, Asiri M.; García Gómez, Hermenegildo (Royal Society of Chemistry, 2015)

[EN] C-dots obtained in the homogeneous phase may exhibit a broad particle size distribution. The formation of C-dots within nanometric reaction cavities could be a methodology to gain control on their size distribution. ...
Luminescence control in hybrid perovskites and their applications

Albero-Sancho, Josep; García Gómez, Hermenegildo (The Royal Society of Chemistry, 2017-05-07)

[EN] Hybrid metal halide perovskites have emerged as promising semiconductor materials for photovoltaic applications as a consequence of their remarkable intrinsic optoelectronic properties and their compositional flexibility. ...
