“…As a result, the self-quenching problem is solved here due to the large Stokes shift of 0.88 eV (Fig. S6), with benefits for their potential applications in luminescent solar concentrators (LSCs) and bio-imaging [41,42]. UPS is a convincible way to determine the valence band and Fermi level positions of semiconductors [43,44].…”

“…As a consequence, semiconductor nanocrystals become a flexible choice to develop a broad a e-mail: isaac.suarez@uv.es range of optoelectronic applications where the absorption and emission of light is required [4]. Examples include waveguides [5], microcavities [6], displays [7], LEDs [8], lasers [9], photodetectors [10], solar cells [11] or optical transistors and memories [12]. For this purpose, their solution process nature enables an easy integration on large areas on different substrates or photonic architectures.…”

Abstract. Semiconductor nanocrystals have arisen as outstanding materials to develop a new generation of optoelectronic devices. Their fabrication under simple and low cost colloidal chemistry methods results in cheap nanostructures able to provide a wide range of optical functionalities. Their attractive optical properties include a high absorption cross section below the band gap, a high quantum yield emission at room temperature, or the capability of tuning the band-gap with the size or the base material. In addition, their solution process nature enables an easy integration on several substrates and photonic structures. As a consequence, these nanoparticles have been extensively proposed to develop several photonic applications, such as detection of light, optical gain, generation of light or sensing. This manuscript reviews the great effort undertaken by the scientific community to construct active photonic devices based on these nanoparticles. The conditions to demonstrate stimulated emission are carefully studied by comparing the dependence of the optical properties of the nanocrystals with their size, shape and composition. In addition, this paper describes the design of different photonic architectures (waveguides and cavities) to enhance the generation of photoluminescence, and hence to reduce the threshold of optical gain. Finally, semiconductor nanocrystals are compared to organometallic halide perovskites, as this novel material has emerged as an alternative to colloidal nanoparticles.

“…This is shown by the research on "Large-area luminescent solar concentrators", made by a research team from the University Milano-Bicocca in collaboration with the Los Alamos National Laboratory (U.S.A.). The team has developed solar concentrators: these are simple slabs of plexiglass "doped" with special fluorescent nanoparticles that capture and concentrate sunlight transforming the windows of buildings in clean energy generators, without giving up the transparency of the material [18].They consist of a semitransparent glass or plastic waveguide doped or coated with highly emissive chromophores, which upon absorption of sunlight re-emit photons at longer wavelengths. Total internal reflection guides the luminescence to the waveguide edges, where it is converted into electricity by PV cells installed along the slab perimeter (Fig.13).…”

Abstract. Internal environment and appropriate natural lighting of the building interior largely affects the health status and course of treatment of patients with psychiatric diagnoses such as depression, Alzheimer and disorder of functions. In particolar, this paper aims to show how smart glass surfaces, allowing the entry of natural lighting, can better support therapeutic process. It is important to elaborate knowledge for optimized lighting conditions in different healthy populations as well as in patients suffering from visual impairments and circadian rhythm disorders. To contribute to the development of new technologies about smart glass surfaces related to various aspects of light conditions for different populations and patients. In the process of preparation of architectural guidelines, it is essential to summarize the findings of the researchers, technologiest, designers, doctors and other related professionals working in particular environments and based on their incentives to specify requirements the architectural or technical design of the space for elederly people.
