A novel, contactless optical sensor of pressure based on the luminescence red-shift and bandwidth (full width at half-maximum, fwhm) Ce3+-doped fluorapatite-Y6Ba4(SiO4)6F2 powder has been successfully synthesized via a facile solid-state method. The obtained material exhibits bright blue emission under UV light excitation. It was characterized using X-ray diffraction, scanning electron microscopy spectroscopy, including high-pressure measurements excitation spectra, up to above ∼30 GPa....
Abstract Single‐phase KL aSr 3 ( PO 4 ) F: Sm 3+ phosphors with fluorapatite structure were prepared via high‐temperature solid‐state method in air atmosphere for the first time. The X‐ray diffraction, scanning electron microscope, diffuse reflectance spectra, photoluminescence and temperature‐dependent emission as well lifetimes measured to characterize as‐prepared phosphors. Phase results indicated that belongs hexagonal system a space group of P ‐6. Photoluminescence measurements showed...

Single-phase CaSr2(PO4)2:Sm3+,Li+ phosphors were prepared via a high-temperature solid-state method under air. The powder X-ray diffraction patterns, scanning electron microscopy images, photoluminescence spectra, and concentration-dependent emission spectra measured to characterize the as-prepared luminescence decay curves. results showed that exhibited red luminescence, of consisted four sharp peaks at around 565, 601 (the strongest one), 647 707 nm. optimum doping concentration Sm3+ ions...
Abstract Optical manometry is a highly promising method for measuring pressure. However, its wider application limited by the lower sensitivity and influenced environmental factors. Herein, multi‐mode optical pressure sensors based on Eu 2+ ‐doped Li 4 SrCa(SiO ) 2 phosphors suitable variety of complex pressure‐measuring environments are designed. The contain two separate luminescence centers at 443 nm (Eu Sr 584 Ca ), respectively. In range, emission peak undergoes massive redshift 5.19 GPa...
The self-reduction mechanism in pyrophosphate phosphors is currently explained through nonequivalent substitution for charge compensation. Nevertheless, the impact of oxygen vacancies on enhancement requires further investigation. Herein, heterovalent Ba1-xZn1-yP2O7:xEu2+/3+, yMg with rigid structures were prepared conventional solid-phase technology air. cation strategy leads to different chemistry electronegativity and adjustable crystal field environments creates vacancy defects. Crystal...
Whitlockite has the advantages of a low sintering temperature, high stability, and fabrication cost, it is widely used as host for luminescent material. In this study, Ca1.8Li0.6La0.6-x(PO4)2:xDy3+ phosphor was prepared by high-temperature solid-state method, its structure, composition, luminescence properties were systematically studied. The results showed that new whitlockite type matrix replacing Ca2+ in with monovalent trivalent cations. phosphors belonged to hexagonal crystal system...
In this study, we investigated the structure, luminescence properties and morphology of La6Ba4(SiO4)6F2:Dy3+ in detail using X-ray diffraction (XRD), photoluminescence spectroscopy, scanning electron microscopy (SEM) decay kinetics measurements. The results indicate that was well crystallized, its structure is apatite-type belongs to hexagonal system. prepared samples exhibit two intense characteristic bands blue (484 nm) yellow (579 spectral ranges corresponding Dy3+ transitions 4F9/2 →...
