The RSrCoFeO₆ (R =
Sm, Eu) samples were prepared by using the solid-state
reaction process. First, the precursor oxides Sm₂O₃ (Alfa Aesar, 99.9% REO), Eu₂O₃ (Alfa
Aesar, 99.9% REO), SrCO₃ (Merck), Co₂O₃ (Merck, >99%), and Fe₂O₃ (Merck, >99%)
were
mixed in the proper stoichiometric ratio. Afterward, we placed the
mixture together with 20 zirconia balls (∼5 mm diameter) in
a Retsch PM100 planetary ball mill at 450 rpm for 30 min (dry without
a medium). Finally, the powder was thermally treated for 12 h at 1100
°C in an air atmosphere, thus obtaining the final compounds.

A series of Ba₀.₉₈SiO₃:0.02Eu, Ba₀.₉₆SiO₃:0.02Eu, and 0.02R (R = Li, K, Na, La, and Y) phosphors were prepared using a conventional solid-state reaction. The BaCO₃ (99+%), SiO₂ (particle size 5~20 nm, 99.5%), Eu₂O₃ (99.99%), K₂CO₃ (99+%), Li₂CO₃ (99+%), Li₂O (97%), Na₂CO₃ (99+%), LaCl₃ (99.99%), and Y₂O₃ (99.99%), purchased from Merck, were used as a raw materials but SiO₂ was used 20% more to obtain a single-phase BaSiO₃ sample. The raw materials were thoroughly mixed in an agate mortar and subsequently fired in air at 1100 °C for 4 h to synthesize the Eu³⁺-doped BaSiO₃. The BaSiO₃:Eu²⁺ samples were prepared by sintering the BaSiO₃:Eu³⁺ samples again under a reduction atmosphere (95% N₂ + 5% H₂) at 1200 °C for 6 h. The specific formulations of the studied samples are shown in Table 1.
The crystal phase of the obtained samples was identified using an X-ray diffractometer (X’Pert PRO MPD-3040, Malvern Panalytical, Malvern, UK, CuK_α1, λ = 1.5406 Å) operating at 40 kV and 30 mA with a scan speed of 0.02°/sec. The photoluminescence excitation (PLE) and emission (PL) spectra were measured using a fluorescent spectrofluorometer (JASCO FP-8500, JASCO, Tokyo, Japan) equipped with an integrating sphere (ISF-834, JASCO, Tokyo, Japan). All measurements were performed at room temperature.

Eu 2 O 3 (Merck, purity > 99.99%) was dissolved in nitric acid which was evaporated to dryness and 0.1 M HNO 3 was added to the solid residue. The concentration of Eu(III) was standardized by complexometric titration with EDTA using xylenol orange as the indicator. The Eu(III) in nitric acid was evaporated to dryness and an FAH-water mixture (50 wt%) was added to obtain the desired Eu(III) concentration.

Analytical graded Y₂O₃ (99.99%), Eu₂O₃ (99.99%), Gd₂O₃ (99.99%), HNO₃ (70.0%), and urea (99.0%–100.5%) were purchased from Sigma-Aldrich (St. Louis, MO, USA) and used as received. Spherical Y₂O₃ nanoprobes co-doped with Eu³⁺ and Gd³⁺ were fabricated using a urea homogeneous precipitation method using the reported protocols [8 (link),9 (link),10 (link),11 (link),12 (link)]. Briefly, a sealed beaker with a freshly prepared aqueous solution of rare-earth nitrates (0.0005 mol in 40 mL of H₂O) was placed into an electrical furnace and heated to 90 °C for 1.5 h. The dried synthesized precipitates were then calcined in air at 800 °C for 1 h to produce the oxide NPs. In all cases, the Eu³⁺ doping concentration was kept constant at 1 mol %, whereas the Gd³⁺ concentration was varied from 0 to 10 mol %.

Eu₂O₃, Pr₂O₃ (Sigma-Aldrich, St. Louis, MO, USA, 99.99% purity), CuO (Alfa-Aesar, Haverhill, MA, USA, 99.999% purity), and BaCO₃ (POCH, Gliwice, Poland, 99.6% purity) were used to prepare the Eu₁₋_xPr_xBCO samples. First, the materials were synthesized by a conventional solid-state reaction method by calcining the stoichiometric weighed substrates at 950 °C for 24 h. Then, the sinters were crushed, ground, and calcination was repeated. Next, sintered materials were ground again and pelletized under a uniaxial pressure of 800 MPa. Finally, the pellets were annealed in an oxygen flow of 20 L/h at 920 °C. After 33 h, the temperature was lowered to 400 °C and held for the next 33 h, as described [8 (link),9 (link),30 ].

The red-emitting GdYGd:Eu³⁺ phosphor was obtained by applying a simple sol–gel method using the initial materials, including Y₂O₃ (Sigma-Aldrich 99.99%), Eu₂O₃ (Sigma-Aldrich 99.99%), Gd₂O₃ (Sigma-Aldrich 99.99%), H₃BO₃ (Sigma-Aldrich 99.99%), C₆H₈O₇·H₂O (Sigma-Aldrich 99.99%) and HNO₃ (Merck, 67%). First, Y₂O₃, Eu₂O_3, and Gd₂O₃ oxides were magnetically stirred at room temperature in an HNO₃ solution for 60 minutes to dissolve completely. During this process, H₃BO₃ and C₆H₈O₇·H₂O solutions were gradually dropped to obtain a transparent solution. Then, this solution was continuously stirred at 120 °C for 6 h to obtain a wet gel product. The wet gel was also stirred at 200 °C for 5 h to obtain a dry gel. The dry gel was ground using an agate mortar for 30 minutes in the next step. Finally, the received product was annealed at 600–1200 °C in the air for 5 h to achieve the final GdYGd:Eu³⁺ phosphor powders.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
