Inhibition of light emission from the metastable tetragonal phase at low temperatures in island-like films of lead iodide perovskites
Chuliá-Jordán, Raquel; Fernández Delgado, Natalia; Juarez-Perez, Emilio Jose; Mora-Sero, Ivan; Herrera Collado, Miriam; Molina, Sergio I.; Martínez-Pastor, Juan P. Royal Society of Chemistry (2019)Photonic applications based on halide perovskites, namely CH3NH3PbI3 (MAPbI3), have recently attracted remarkable attention due to the high efficiencies reported for photovoltaic and light emitting devices. Despite these ... -
Purcell Enhancement and Wavelength Shift of Emitted Light by CsPbI3 Perovskite Nanocrystals Coupled to Hyperbolic Metamaterials
Pashaei Adl, Hamid; Gorji, Setatira; Karimi Habil, Mojtaba; Suárez, Isaac; Chirvony, Vladimir; Gualdrón Reyes, Andrés Fabián; Mora-Sero, Ivan; Valencia, Luisa M.; de la Mata, María; Hernández Saz, Jesús; Molina, Sergio I.; Zapata-Rodriguez, Carlos J.; Martínez-Pastor, Juan P. American Chemical Society (2021-11-18)Manipulation of the exciton emission rate in nanocrystals of lead halide perovskites (LHPs) was demonstrated by means of coupling of excitons with a hyperbolic metamaterial (HMM) consisting of alternating thin metal (Ag) ... -
Solution-Processed Ni-Based Nanocomposite Electrocatalysts: An Approach to Highly Efficient Electrochemical Water Splitting
Noguera-Gomez, Jaume; García-Tecedor, Miguel; Sánchez Royo, Juan Francisco; Valencia, Luisa M.; de la Mata, María; Herrera Collado, Miriam; Molina, Sergio I.; Abargues, Rafael; Gimenez, Sixto American Chemical Society (2021-05-10)In this study, we report an up-scalable and low-cost solution-processed method to in situ synthesize an earth-abundant non-stoichiometric NiOx-based electrocatalytic film for water oxidation. The catalytic activity was ...
