Power dependence of upconversion luminescence
1999Spectroscopic data are of essential value for understanding the excitation mechanisms in luminescent and laser materials. Special attention has been devoted to the investigation of upconversion-induced luminescence, partly because of the availability of near-infrared pump sources for the excitation of visible luminescence and laser emission and partly ...

General Introduction to Upconversion Luminescence Materials
2014Upconversion nanoparticles can emit ultraviolet/visible/near-infrared light under near-infrared excitation (anti-Stokes emission). This unique optical property precludes background fluorescence and light scattering from biological materials. The emission of multiple and narrow emission lines is an additional hallmark of upconversion nanoparticles that ...

Orthogonal Upconversion Luminescence from Core/Shell-Structured Upconversion Nanophosphors
ECS Meeting AbstractsUpconversion nanophosphors (UCNPs) are lanthanide ion-doped nanocrystals that exhibit anti-Stokes shift luminescence. Typically, UCNPs such as NaYF4:Yb,Er and NaYF4:Yb,Tm emit green and blue light under 980 nm near-infrared (NIR) light excitation. The emission color of lanthanide ion-doped UCNPs depends on the dopant ions in the host nanocrystals ...
