Er3+/Yb3+ co-doped materials have been extensively used for imaging in biomedical applications using either visible up-converted (UC) or near-infrared (NIR) emissions. The UC spectrum is composed mainly by two Erbium emissions in the green (2H11/2:4S

The energy transfer mechanisms between Er3+ and Yb3+ ions have been investigated in LiLa9(SiO4)6O2 under selective Er3+ excitation. IR emission spectra, measured in the CW excitation regime, were used to establish a relationship between the macroscop

Two new white-light (WL)-emitting phosphors (δ-Gd2Si 2O7:Dy and δ-Gd2Si2O 7:Eu,Tb) have been synthesized by the sol-gel method. The Gd-Ln 3+ (Ln3+= Dy3+, Tb3+, Eu 3+) energy-transfer band has been used to excite both phosphors, which provides an en

Monoclinic Tb:CePO4 nanophosphors with a spindle-like morphology and tailored size (in the nanometer and micrometer range) have been prepared through a very simple procedure, which consists of aging, at low temperature (120 C), ethylene glycol soluti
