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

Synthesis and up-conversion luminescence properties of Er3+/Yb3+ co-doped Sr2CeO4 phosphors

“…Sr 2 CeO 4 is a promising blue emitting oxide-based phosphor characterized by its high thermal and chemical stability and excellent optical properties [20]. Furthermore, Sr 2 CeO 4 has a low phonon energy of 561 cm -1 [21], which is very low compared with that of other oxide host such as Y 3 Al 5 O 12 (850 cm -1 ) [22]. It is well known that a host lattice with low phonon energy will increase the UC emission efficiency due to its low multiphonon relaxation rate [23].…”

Electronic properties and europium ion photoluminescence behaviors in Sr2CeO4 phosphor

“…An unusual blue phosphor Sr 2 CeO 4 was first prepared using the combinatorial techniques by Danielson et al in 1998 [5]. Since then, many advanced synthesis techniques such as Pechini's method [6], spray pyrolysis [7], emulsion liquid membrane system [8], ethylenediaminetetraacetic acid (EDTA)-complexing process [9], microwave-assisted solvothermal process [10] have been developed to prepare the Sr 2 CeO 4 phosphor because of its efficient luminescence under ultraviolet, cathode ray and X-ray excitation [11,12].…”

Synthesis of Sr2SiO4 nanometer particles from the core–shell precursor of SrCO3/SiO2

“…1 shows FT-IR spectrum of the SrCO 3 /SiO 2 core-shell precursor. The absorption peaks at 1768, 1450, 1070, 860, 706 and 699 cm −1 are assigned to SrCO 3 stretching characteristics [12]. Si-O-Si (800 cm −1 [13] and 1000-1200 cm −1 [14]) and Si-OH (970 cm −1 [15]) were also observed, indicating the formation of SiO 2 with a small amount of silanol groups.…”
