Preparation and characterization of fine Sr2CeO4 blue phosphor powders

Subsolidus phase relations of the SrO–REOx–CuO systems (RE=Ce, Pr and Tb)

“…Only the sample with x = 0.00 was free of both Ce 1−x Sr x O 2−δ and Sr 2 CeO 4 in agreement with the results of Longo et al [21]. Sr 2 CeO 4 is not stable above 1430 K [21] but can be synthesised at 1273-1373 K in air [22,[24][25][26]. This compound is also stable under the conditions used for the present study.…”

Synthesis and luminescent property of Sr2CeO4 phosphor via EDTA-complexing process

“…Fig. 4(a) shows the TEM image of Sr 2 CeO 4 calcined at 800 • C. The obtained powders are highly porous, and the particles are linked together by crotch-like way, which is similarly observed by a PEG-2000 sol-gel route [1] and an emulsion liquid membrane system [7]. However, The average lengths and diameters of Sr 2 CeO 4 particles via EDTA-complexing process are smaller than those prepared by the above-mentioned methods.…”

“…5(a), the excitation bands slightly shift towards high wavelength with the increasing temperature, which is different from that reported in Refs. [1,14]. O.A.…”

“…The development of phosphors for the three primary colors attracts considerable interests in recent years due to their potential technological applications such as high-performance fluorescent lights and high-resolution display devices [1,2]. Red-emitting Y 2 O 3 :Eu 3+ and green-emitting Y 3 Al 5 O 12 :Tb 3+ , Y 3 Al 5 O 12 :Ce 3+ , have found many extensive applications [3,4].…”

Luminescence properties of sol–gel derived Sr2(Ce1−Sn )O4 blue phosphors

“…Fig. 8 [9,26], indicating that the excitation and emission bands for Sr 2 (Ce 1−x Sn x )O 4 phosphors were completely ascribed to the ligand-to-metal and metal-to-ligand charge transfers, respectively. Fig.…”
