Elaborate design of energy transfer systems in luminescent nanocrystals revealed tremendous advantages in nanotechnology, especially in biosensing and drug delivery systems. Recently, upconversion nanoparticles have been discussed as promising probes as labels in biological assays and imaging. This article reviews the works performed in the recent years using quantum dot- and rare-earth doped nanoparticle-based energy transfer systems for biomedical applications.

Rare-earth doped β-NaYbF4upconversion phosphors were synthesized using a simple hydrothermal procedure. It is found that under 980 nm excitation β-NaYbF4:0.1%Tm are more efficient than β-NaYF4:20%Yb,0.1% that is known as one of the most effective upconversion materials. The unusual result may be related to the particles size. After introducing 0.1%Er3+into the NaYbF4:0.1%Tm lattice, the upconversion white emission with color coordinate of (0.3016,0.3748) is obtained. The investigation of achieving mechanism indicates that besides the energy transfer from Yb3+to Tm3+and Er3+, respectively, there exists a new energy transfer process:3F2,3(Tm3+) +4I11/2(Er3+) →3F4(Tm3+) +2H11/2/4S3/2(Er3+).
