Fabrication and Luminescence Properties of Transparent Glass‐Ceramics Containing Eu³⁺‐Doped TbPO₄ Nanocrystals

Abstract

Eu3+ -doped transparent phosphate precursor glasses and glassceramics containing TbPO 4 nanocrystals were successfully fabricated by a conventional high-temperature melt-quenching technique for the first time. The formation of TbPO 4 nanocrystals was identified through X-ray diffraction, transmission electron microscopy, high-resolution transmission electron microscopy, selected-area electron diffraction, and photoluminescence emission spectra.

Transparent glass ceramics containing Lu6O5F8:Tb3+ nano‐crystals: Enhanced photoluminescence and X‐ray excited luminescence

“…As shown in Figure B, the UV‐VIS absorption spectra PG1 and GCx indicate that PG1 and GC samples are transparent in visible region due to the smaller size of crystallized Lu 6 O 5 F 8 nano‐crystals compared to the wavelength of visible light, which can be seen from the photograph of all samples (Inset of Figure ). Fair transparency favors light extraction and their scintillating applications.…”

Up-conversion luminescence and optical thermometry properties of transparent glass ceramics containing CaF2:Yb3+/Er3+ nanocrystals

“…The average nanocrystal sizes of GC are much smaller than the wavelength of visible and near-infrared light, so the scattering remains weak and the GCs are highly transparent [21]. As depicted in Fig.…”

Transparent glass–ceramics with (Eu3+,Yb3+):YNbO4 nanocrystals: Crystallization, structure, optical spectroscopy and cooperative upconversion

“…It is used in commercial blue phosphors, such as BaMgAl 10 O 17 [11]. Various dielectric hosts in the form of nano-powders [12][13][14][15][16], films [17][18][19], crystals [20][21][22], glasses [23][24][25][26][27] and glass-ceramics (GCs) [28][29][30][31][32][33][34][35][36][37] were studied for Eu-doping to improve the emission efficiency, as well as to tune the color properties; and the list is ever growing.…”
