“…Doped oxyfluoride glass and glass‐ceramics are being studied due to their possible uses as scintillators, thermoluminescent dosimeters, in optical applications such as waveguides, fluorescent concentrators, and as optical temperature sensors . In particular, oxyfluoride glass‐ceramics materials combine advantages of the oxide matrix with optical attributes of low‐phonon fluoride crystals.…”

Oxyfluoride glass and glass‐ceramics are being studied due to the possibility of their utilization in many applications, such as thermoluminescent dosimeters, optical fibers, fluorescent concentrators, and temperature sensors. In order to improve the properties of glass, they are often crystallized. For this crystallization to be effective, knowledge and control of the structure of the starting material is required. Much work was done on silicate glass; however, a great interest exists in obtaining these kinds of materials in other matrices such as germanates, phosphates, and borates. Here, we present a structural study of some oxyfluoride borate glass with different concentrations of PbF2 by means of Nuclear Magnetic Resonance (NMR), Raman, and Fourier Transform Infrared (FTIR) spectroscopies. We also analyzed glass‐crystallization using Differential Scanning Calorimetry (DSC). The crystallization study was complemented with the use of Transmission Electron Microscopy (TEM) and Selected Area Electron Diffraction (SAED), for the purpose of identifying possible mechanisms of crystallization. Our results indicate, from the structural point of view, that the glass present groups with one or two BO4 species, such as diborate or pentaborate. The small variation in the BO4 fraction with the increase in PbF2 concentration would be an indication of the formation of F−BO3/2 species. Oxyfluoride borate glass containing BaO as a cation modifier and 30% PbF2 represents a good starting point for obtaining glass‐ceramics with a narrow size distribution of BaF2 nanocrystals. We also propose that the possible mechanism for oxyfluoride borate glass crystallization started with a separation of phases.

“…In the field of solar energy, luminescent materials are commonly employed in the socalled luminescent solar concentrators (LSCs). [6][7][8][9][10][11][12][13][14][15] A conventional LSC consists of a few millimeters thick plastic waveguide which is doped with one or more luminescent compounds.…”

A multifunctional, semitransparent photovoltaic device is proposed for\ud harvesting sunlight over a tunable spectral range extending from the UV to\ud the IR. Self-assembled monolayers of nanospheres applied to luminescent\ud concentrators provide a photon management architecture, which relies\ud on luminescence and diffraction of light. The light diffraction is tuned by\ud changing the sphere diameter to match the transparency region of the\ud fl uorophores. The importance of each optical mechanism is inferred from\ud a systematic experimental investigation of the external quantum effi ciency\ud of fabricated devices, and from the calculation of the resulting photocurrent\ud under the AM 1.5 solar spectrum. Compared to the conventional\ud luminescent concentrator, relative photocurrent improvements are shown\ud between 50% and 500% depending on the spectral properties of the device\ud components. It has been demonstrated how to tailor the photovoltaic performances,\ud the color and the degree of transparency of the device to provide a\ud versatile photovoltaic unit for sustainable building-integrated applications
