The Hidden Effects of Particle Shape and Criteria for Evaluating the Upconversion Luminescence of the Lanthanide Doped Nanophosphors

The dependences of upconversion luminescence (UCL) on the particle size, shape, and inorganic−ligand interface of the hexagonal (β)-phase NaYF4:Yb,Er upconversion nanophosphors (β-UCNPs) were studied. The photophysical data, e.g., relative UCL intensity, power-dependent UCL, green to red emission in...
