Spectral and surface investigations on Eu3+ doped K3Y(PO4)2 nanophosphor: A promising orange–red phosphor for white light-emitting diodes

Flux Synthesis, Monoclinic Structure, and Luminescence of Europium(III)‐Doped K3La(PO4)2

“…Such an effect can be related to the absorption of the phosphate host. It is well known that the absorption (excitation) spectra of double phosphates in the 200–300 nm region are very complex in nature and difficult to interpret, due to overlap of the Eu 3+ ‐ charge transfer band and various bands associated with point defects. Thus, the photoluminescence excitation band in the 250–300 nm region is more likely to be a superposition of the band‐to‐band transition of the phosphate host and O 2− →Eu 3+ charge‐transfer transition and the contribution of the former decreasing with the increase in the Eu 3+ concentration.…”

Novel rod-Y2O3:Eu3+@0.01YVO4:Eu3+ with open core/shell nanostructure and “off-and-on” fluorescent performance

“…Rare-earth-doped nano-phosphors have unique properties and applications in many elds, such as white light-emitting diodes, eld emission displays, and general uorescence lamps. [1][2][3][4][5][6][7] They are highly popular among researchers and are gaining increasing importance in our daily lives. Y 2 O 3 :Eu 3+ and YVO 4 :Eu 3+ are well-known red-emitting phosphors.…”
