“…[156] Higher quantum yields have been found in quartz-like (FQY = 50%), pentalite-like (FQY = 75%), and gahnite (FQY = 100%) glass ceramics. [157,158] Chromium(III) ions can be used for codoping neodymium-and ytterbium-doped glasses, as they increase the absorption range of the glass and then transfer their energy to the high-quantumyield neodymium and/or ytterbium ions. The energy-transfer efficiencies from chromium(III) to neodymium and ytterbium have been determined at 92% and 88% respectively in lithium lanthanum phosphate (LPP) glasses.…”

“…Chromium(III) ions have a large spectral absorption with peaks at 450 nm ( 4 A 2 → 4 T 1 ) and 650 nm ( 4 A 2 → 4 T 2 ) and so could be useful for LSCs, but a major drawback is the limited quantum efficiency (up to 25%) 156. Higher quantum yields have been found in quartz‐like (FQY = 50%), pentalite‐like (FQY = 75%), and gahnite (FQY = 100%) glass ceramics 157, 158. Chromium(III) ions can be used for codoping neodymium‐ and ytterbium‐doped glasses, as they increase the absorption range of the glass and then transfer their energy to the high‐quantum‐yield neodymium and/or ytterbium ions.…”

Research on the luminescent solar concentrator (LSC) over the past thirty‐odd years is reviewed. The LSC is a simple device at its heart, employing a polymeric or glass waveguide and luminescent molecules to generate electricity from sunlight when attached to a photovoltaic cell. The LSC has the potential to find extended use in an area traditionally difficult for effective use of regular photovoltaic panels: the built environment. The LSC is a device very flexible in its design, with a variety of possible shapes and colors. The primary challenge faced by the devices is increasing their photon‐to‐electron conversion efficiencies. A number of laboratories are working to improve the efficiency and lifetime of the LSC device, with the ultimate goal of commercializing the devices within a few years. The topics covered here relate to the efforts for reducing losses in these devices. These include studies of novel luminophores, including organic fluorescent dyes, inorganic phosphors, and quantum dots. Ways to limit the surface and internal losses are also discussed, including using organic and inorganic‐based selective mirrors which allow sunlight in but reflect luminophore‐emitted light, plasmonic structures to enhance emissions, novel photovoltaics, alignment of the luminophores to manipulate the path of the emitted light, and patterning of the dye layer to improve emission efficiency. Finally, some possible ‘glimpses of the future’ are offered, with additional research paths that could result in a device that makes solar energy a ubiquitous part of the urban setting, finding use as sound barriers, bus‐stop roofs, awnings, windows, paving, or siding tiles.

“…Transparent glass-ceramics have a lot of advantages, such as almost zero thermal expansion, fine thermal conductivity, high transmittance at the laser wavelength, the superior chemical stability and high resistance to hot shock, and they have potential to substitute the single crystals and glass in laser field in the near future. B 2 O 3 -Al 2 O 3 -SiO 2 (BAS) system glass-ceramics were attracted commencing from 1980s [6,7]. BAS system glass-ceramics doped Cr 3+ were researched and developed as laser materials owning to the development of laser technique [8][9][10].…”

“…Transparent glass-ceramics based on fluoride [8][9][10][11][12], oxyfluoride [13][14][15][16][17][18][19][20][21][22][23][24][25][26], chalcogenide [27,28] glasses, and doped by rare-earth ions are successfully used for wavelength up-conversion devices, for erbium doped waveguide amplifiers [29]. Transparent mullite [30][31][32][33], spinel [33][34][35][36][37][38], gahnite [3,33,35,39], willemite [39,40], forsterite [41] and gehlenite [42] based glass-ceramics doped with transition metal ions were developed for use in broadband optical amplification, tunable and infrared lasers and in solar collectors [43][44][45][46][47][48][49][50]...…”
