The hydroxyapatite nanopowders of the Eu3+-doped, Cu2+-doped, and Eu3+/Cu2+-co-doped Ca10(PO4)6(OH)2 were prepared by a microwave-assisted hydrothermal method. structural morphological properties products investigated X-ray powder diffraction (XRD), transmission electron microscopy techniques (TEM), infrared spectroscopy (FT-IR). average crystal size unit cell parameters calculated Rietveld refinement tool. absorption, emission excitation, emission, luminescence decay time recorded studied...
The β-KYP2O7 powders doped with Sm3+, Tb3+ and Dy3+ were obtained using a one-step urea-assisted combustion method. Their structural properties characterized by X-ray diffraction (XRD) whereas spectroscopic like excitation, emission luminescence kinetics investigated at room temperature. Sm3+ showed concentration quenching above 2 mol% of dopants containing materials could be higher concentrations. main mechanisms identified as dipole–dipole for Dy3+. Both due to the abundant energy levels...
This paper discusses the origin of emission quenching in yttrium orthovanadate codoped with Eu
Yttrium gallium garnet (YGG) submicrocrystals having 80 nm average diameters doped with Cr3+ (0.1–40%) were synthesized by the citrate method. Pure cubic garnets obtained in wide range (0.1–15%) of dopant concentration. Chromium ions replace Ga3+ at octahedral sites and experience an intermediate or weak crystal field, depending only on The field is observed when concentration exceeds 3%. origin such behavior discussed.
KYP2O7 powders doped with Eu3+ were obtained for the first time by a one-step urea-assisted combustion method. Detailed structural properties characterized X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM) and fluorescence (EDX). Spectroscopic like excitation, emission luminescence kinetics investigated in temperature range of 30–550 °C. The phosphor has broad intense absorption band centered at 213 nm, an absolute quantum yield up to 62% quenching T0.5 = 400...
In the present work, a precipitation method was employed to prepare nanosized YAsO4 doped with Eu3+ ions. The raw nanomaterials have been thermally treated in temperature range between 500 and 900 °C for 3 h. XRD analysis demonstrated that powders were single-phase nanopowders high crystallite dispersion. Our studies focused on relating luminescence properties of dopant nanocrystallite (NC) size. average NC size varied accordingly 15 45 nm. We found effect is manifested mainly expansion cell...
La2CaB10O19 powders doped with Eu3+ ions were synthesized using a citric route for the first time. The crystal structure, morphology and chemical composition of engineered compounds characterized in details X-ray diffraction (XRD), Raman spectroscopy, transmission scanning electron microscopy (TEM SAED) fluorescence (EDX). photoluminescence properties (emission, excitation, excited state dynamics) evaluated temperature range 300–700 K. We have found that thermal dependency emission is quite...
Abstract A series of ZnX 2 O 4 :Er 3+ /Yb (X = Al , Ga In ) nanoparticles were obtained by using a modified Pechini technique. The crystal structure, morphology, and chemical composition the engineered compounds characterized in detail means X‐ray diffraction, Micro‐Raman spectroscopy, transmission electron microscopy (TEM) selected area energy‐dispersive spectroscopy. Particle sizes estimated theoretical calculations (Scherrer Rietveld methods) as well experimental techniques [TEM dynamic...
A new very promising red phosphor KCa1-xEux(PO3)3 (x = 1-5%) has been grown by the solid state method. Its luminescent quantum efficiency is close to 100% and emission stable over a wide temperature range i.e. 90% 60% of room intensity remains at 200 °C 600 °C, respectively. The chromaticity coordinates were calculated as being x 0.63, y 0.37. IR Raman spectra measured, maximum phonon energy 1276 cm(-1). In measured excitation all samples only Eu(3+) ion was observed, Eu(2+) not present....
