【Rare-Earth Doped GdVO4 by Sol-Gel Method: Structural and Luminescence Properties】
#论文# #稀土# #发光材料# #发光性能# # 稀土掺杂#
Rare earths (RE) are widely studied due to their unique properties and applications in optoelectronic, antibacterial activity, and other fields. Gadolinium vanadate (GdVO4) is a material with diverse applications. At presennt, several methods have been used to prepare undoped and RE-doped GdVO4. This work shows the results obtained to carry out the synthesis of luminescent powders of GdVO4:Yb3+ (Iterbium), X3+ [X = Tm (Thulium), Er (Erbium) and Ho (Holmium)].
