Synthesis of BaMgAl10O17:Eu2+ particles with small grain size and regular morphology

Luminescence of some Eu2+ activated bromides

“…BaMgAl 10 O 17 :Eu and Sr 5 (PO 4 ) 3 Cl:Eu are efficient tri-colour lamp phosphors [1,2], BaFBr:Eu is used as intensifier for X-ray imaging films [3] as well as for X-ray imaging using photo-stimulated luminescence (PSL) [4], CaSO 4 :Eu is near UV emitting phosphor for photoluminescent liquid crystal displays (PLLCD) [5], SrB 4 O 7 :Eu is an efficient phosphor for tanning lamps [6]. Use of SrMgAl 10 O 17 :Eu [7] and CaMgSi 2 O 6 :Eu [8] has been advocated as blue emitting component of a phosphor blend for plasma display panels (PDP).…”

Preparation of BaMgAl10O17:Eu2+ phosphor with small particle size by co-precipitation method

“…The parameters of the coprecipitation reaction were similar to those of the preparation of small particle size A 2 O 3 powder, only stricter. A more detailed information can be seen in previous reports [28,29].…”

“…Compared with the phase transformation process of the conventional high temperature solid state reaction method [29], the process of co-precipitation method showed large differences:…”

Preparation and luminescent properties of a novel red emitting phosphor of Ca1−2xMxIn2O4:xEu3+ (M=Li, Na, K) for white LED solid-state lighting

“…Recently, the white light emission from Eu 3+ in the CaIn 2 O 4 host under the excitation of 397 nm light has been reported by Liu and co-workers [23,24]. The white light consists of emission lines from transitions of 5 …”

“…Presently, the main commercial red phosphor for near-UV-LED is Y 2 O 2 S:Eu 3+ [3][4]. However, the sulfide red phosphor is chemically unstable and the absorption efficiency in the near-UV-region is not desirable compared to that of the blue (BaMgAl 10 O 17 :Eu 2+ ) [5,6] and the green (ZnS:(Cu + , Al 3+ )) [7] phosphors. Therefore, more attention has been paid to the investigation of the red emitting materials using near-UV-LED as the excitation source in the past few years [8][9][10][11], and it is significant to develop new stable phosphors that emit a more intense component in the red region.…”
