Light Emitting Diodes (LEDs) are revolutionary low energy consumption light sources that entered our everyday life, as they are capable of reducing world’s lighting energy requirements by more than 75%. Additionally they trigger new devices and applications, ranging from transparent displays,1 to optical communication and computing with integrated photonic devices. LED technology can further be improved by engineering its spectral and efficiency properties. Here we present several state-of-the-art nanotechnology and photonics-based approaches that we employ in the framework of functionalization of LEDs with optical active nanomaterials such as Perovskites and Quantum Dots (QDs).2 Furthermore, surface structuring techniques for enhanced out-coupling of radiation3 shall be employed using available advanced 3D nanostructuring techniques, such as femtosecond laser ablation, two-photon polymerization or nanoimprinting. The improved integration via miniaturization at the nanoscale shall ultimately increase the LED versatility and empower new applications.
In this work we study the optical properties of active nanomaterials including colloidal perovskites and Quantum Dots (QD) embedded in different polymer matrices towards stable integration in organic/inorganic nanophotonic LEDs.4 Particularly the dry deposition steps of inorganic layers process are limiting factors. We perform structural and optical characterization of synthetized colloidal CsPbBr3 perovskites using Transmission Electron Microscopy (TEM) and spectrally-resolved confocal fluorescence microscopy imaging. Also, we perform advanced optical characterization of colloidal CdSe/ZnS QD embedded in different polymer matrices using spectrally-resolved confocal fluorescence microscopy, Fluorescence Lifetime Imaging Microscopy (FLIM) and spectrally-correlated streak imaging. Ultimately, we design and fabricate an all-inorganic Alternated Current (AC) LED chip with CdSe/ZnS QD active layer.
Using the advanced optical information for the integrated optical active materials, we provide routes for optimization of LED design and fabrication.

nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
