“…5. The band peaking at 191 nm is related to the charge transfer band (CTB) of Ba 2+ -O 2− [31]. The excitation band with the maximum at 228 nm could be assignable to charge transfer (CT) absorption of Eu 2+ -O 2− [32,33].…”

Eu 2+ -activated Ba 2 P 2 O 7 pyrophosphates were successfully synthesized by the solid-state reaction under reduced atmosphere and were characterized by X-ray diffraction (XRD) and Nuclear magnetic resonance and infrared (IR)/Raman spectroscopy. The luminescence properties of Ba 2−x P 2 O 7 : xEu 2+ (x = 0.01, 0.05) phosphors were investigated in ultraviolet (UV) and vacuum ultraviolet (VUV) regions. Under 131 or 320 nm excitation, the phosphors exhibit a blue emitting band ranging from 350 to 500 nm, which is provided corresponding to the 5d-4f transition of Eu 2+ . The as-synthesized phosphors present good thermal luminescence stability on temperature quenching and high color purity with the CIE coordinate (0.172, 0.031) for Ba 2 P 2 O 7 :1%Eu 2+ phosphor. These results suggest that the Ba 2 P 2 O 7 :Eu 2+ pyrophosphate might be a promising blue-emitting phosphor for near ultraviolet (n-UV) light-emitting diodes (LEDs).

“…CMS is known to be stable and efficient under ultraviolet or vacuum ultraviolet (VUV) excitation. 22) This phosphor shows a broad emission spectrum because its activator sites experience different host lattice crystal fields. The absorption and emission bands of the activator are controlled by the crystal fields of the host lattice.…”

For light-emitting diode (LED) excitation at 400 nm, the optical properties of a Eu 2þ -activated CaO-SrO-MgO-SiO 2 material system were investigated. All the materials were synthesized by solid state reaction. In particular, (Ca,Sr)Mg 2 Si 3 O 9 :Eu 2þ , which has the same crystal structure as CaMgSi 2 O 6 , was found to be promising as a blue-light-emitting phosphor for near UV LED application. The luminance intensity was optimized by controlling the Eu 2þ concentration and the composition of the host lattice. The ratio of calcium ions to strontium ions was a convenient parameter for adjusting the maximum excitation peak to 400 nm, which is favorable for near UV LED excitation. The highest luminance intensity of Ca 1ÀxÀy Sr y Mg 2 Si 3 O 9 :Eu x 2þ under 405 nm excitation was achieved at the Eu 2þ concentration of x ¼ 0:01 and a Sr 2þ concentration of y ¼ 0:3. The luminance intensity of (Ca,Sr)Mg 2 Si 3 O 9 :Eu 2þ was found to be superior to that of a commercial blue-light-emitting BaMgAl 10 O 17 :Eu 2þ phosphor, which is used for near-UV LED excitation. #
