Photonic Tuning of the Emission Color of Nanophosphor Films Processed at High Temperature
Photonics offers new possibilities to tailor the photoluminescence process in phosphor-converted light emitting diodes. Herein, it is demonstrated that the emission color of thin layers of rare-earth doped nanocrystals can be strongly modulated in tunable spectral...
Design and Realization of a Novel Optically Disordered Material: A Demonstration of a Mie Glass
Herein, a diffusive material presenting optical disorder isintroduced, which represents an example of a Mie glass. Comprising spherical crystalline TiO2 nanoparticles randomlydispersed in a mesoporous TiO2 matrix, it is proved that thescattering of light in this...
Electron injection and scaffold effects in perovskite solar cells
In spite of the impressive efficiencies reported for perovskite solar cells (PSCs), key aspects of their working principles, such as electron injection at the contacts or the suitability of the utilization of a specific scaffold layer, are not yet fully understood....
Strong Quantum Confinement and Fast Photoemission Activation in CH3NH3PbI3 Perovskite Nanocrystals Grown within Periodically Mesostructured Films
In this Communication, a synthetic route is demonstrated to obtain stabilized MAPbI3nanocrystals embedded in thin metal oxide films that display well-defined and adjustable quantum confinement effects over a wide range of 0.34 eV. Mesostructured TiO2 and SiO2 films...
