“…The main processes involved are: (i) absorption of the incident light, (ii) re-emission of the absorbed photons, and (iii) photon transport to the plate's edges. This corresponds to the product (Reisfeld and Jorgensen, 1982;Reisfeld et al, 1994;Reisfeld, 2002;Drake et al, 1982;Thomas et al, 1983;Zastrow, 1994):…”

“…The parameter η trap represents the trapping efficiency defined by the refractive index of the matrix, η mat comprises photon transport losses, such as scattering and parasitic absorption by matrix defects, and R is the Fresnel reflection coefficient of the LSC surface. As a model system we employ thin film LSCs, where the photoactive component is dispersed in a PMMA layer on top of a transparent glass support (Reisfeld and Jorgensen, 1982;Reisfeld et al, 1994;Reisfeld, 2002). The perylene dye Lumogen F Red 305 (hereafter referred to as Red 305) is well suited for application in LSCs, as the absorption covers a large part of the visible range Kinderman et al, 2007;Slooff et al, 2008;Meyer and Markvart, 2009).…”

“…[24][25][26][27][28][29][30] In general, the embedding of organic dyes, quantum dots (QDs), and trivalent lanthanide (Ln 3+ ) complexes into hybrid hosts, with the corresponding formation of covalent (Class II) or noncovalent (Class I) [31] host-guest interactions, improves the thermal stability, the mechanical resistance, and the aging and environmental stability of the guest emitting centers, relatively to what is observed for isolated centers. [32,33] Moreover, the dispersion of these centers within the hybrid framework allows their incorporation in larger amounts, isolated from each other and protected by the hybrid host, improving the emission quantum yield and preventing the emission degradation. [34][35][36][37][38] In this section, we cover recent developments of luminescent and electroluminescent hybrid materials, with particular emphasis to specific applications, such as LEDs, random and feedback lasers, luminescent solar concentrators (LSCs), and luminescent thermometers.…”

Research on hybrid inorganic‐organic materials has experienced an explosive growth since the 1980s, with the expansion of soft inorganic chemistry based processes. Indeed, mild synthetic conditions, low processing temperatures provided by “chimie douce” and the versatility of the colloidal state allow for the mixing of the organic and inorganic components at the nanometer scale in virtually any ratio to produce the so called hybrid materials. Today a high degree of control over both composition and nanostructure of these hybrids can be achieved allowing tunable structure‐property relationships. This, in turn, makes it possible to tailor and fine‐tune many properties (mechanical, optical, electronic, thermal, chemical…) in very broad ranges, and to design specific multifunctional systems for applications. In particular, the field of “Hybrid‐Optics” has been very productive not only scientifically but also in terms of applications. Indeed, numerous optical devices based on hybrids are already in, or very close, to the market. This review describes most of the recent advances performed in this field. Emphasis will be given to luminescent, photochromic, NLO and plasmonic properties. As an outlook we show that the controlled coupling between plasmonics and luminescence is opening a land of opportunities in the field of “Hybrid‐Optics”.

“…LSCs are basically plastic or glass waveguides containing or topped with a thin layer of fluorescent materials, like organic dyes [4][5][6] or quantum dots [7][8][9][10]. These luminophores absorb incident sunlight and re-emit these photons at longer wavelengths.…”

Increased efficiency of luminescent solar concentrators after application of organic wavelength selective mirrors

Organic wavelength-selective mirrors are used to reduce the loss of emitted photons through the surface of a luminescent solar concentrator (LSC). A theoretical calculation suggests that application of a 400 nm broad reflector on top of an LSC containing BASF Lumogen Red 305 as a luminophore can reflect 91% of all surface emitted photons back into the device. Used in this way, such broad reflectors could increase the edgeemission efficiency of the LSC by up to 66%. Similarly, 175 nm broad reflectors could increase efficiency up to 45%. Measurements demonstrate more limited effectiveness and dependency on the peak absorbance of the LSC. At higher absorbance, the increased number of internal re-absorption events reduces the effectiveness of the reflectors, leading to a maximum increase in LSC efficiency of ~5% for an LSC with a peak absorbance of 1. Reducing re-absorption by reducing dye concentration or the coverage of the luminophore coating results in an increase in LSC efficiency of up to 30% and 27%, respectively.
