Abstract

This work investigated the near-infrared (NIR) emission properties of mCe 3+ , xNd

Efficient Near‐Infrared Emission of Ce3+–Nd3+ CoDoped (Sr0.6Ca0.4)3(Al0.6Si0.4)O4.4F0.6 Phosphors for c‐Si Solar Cell

“…7 It means that blue light in natural light is partly absorbed, and the reflected light forms its light yellow body color. 22 For the Nd 3+ single or codoped sample, two peaks located from 500 to 620 nm appear. As stated above, the two peaks belong to the Nd 3+ ion.…”

“…The Ce 3+ doped samples show two absorption peaks in the range from 330 to 450 nm, obviously, they result from the f – d transitions of Ce 3+ ion . It means that blue light in natural light is partly absorbed, and the reflected light forms its light yellow body color . For the Nd 3+ single or codoped sample, two peaks located from 500 to 620 nm appear.…”

Enhanced Near-Infrared Luminescence in Ba3Y(BO3)3: Nd3+ by Codoping with Ce3+

“…However, the NIR emission of Nd 3+ ions rises first and then drops continuously after x = 0.035 because of concentration quenching. 25,26 The gradual decrease of visible light emission intensity indicates the existence of ET from Ce 3+ to Nd 3+ . The illustration clearly illustrates the relationship between normalized integrated emission and doping concentration, and the optimal doping concentration of Nd 3+ ion is 0.035.…”

Tunable emission color and mixed valence state via the modified activator site in the AlN-doped Sr3SiO5:Eu phosphor

“…Hence, efforts have been devoted to improving the intensity in red spectral region through partial substitution like (Sr,Ba,Mg) 3 SiO 5 :Eu 2+ and Sr 3 SiO 5 :Ce 3+ ,Eu 2+ ,Al 3+ . [25][26][27][28] In this work, we synthesized a series of Sr 2.97 Si 1Àx Al x O 5À2x N x :0.03Eu (x ¼ 0-0.5) phosphors under a reducing atmosphere. The obtained samples presented not only broad excitation bands (ranging from 250 to 400 nm) but also tunable emission colors, originated from the characteristic emissions of Eu 2+ and Eu 3+ .…”
