Cancer treatment using conventional drug delivery platforms may lead to fatal damage to
normal cells. Among various intelligent delivery platforms, photoresponsive delivery …

As a potential photosensitizer for photodynamic therapy (PDT), pure titanium dioxide has the
drawbacks of low tissue penetration and possible damage to skin due to the triggered UV …

In this work, hexagonal phase NaY (Gd0. 4) F4: Yb3+/Ho3+ nanocrystals were obtained by
solvothermal method. The upconversion emission tuning from green to red in NaY (Gd0. 4) …

Internal OH–defects always cause significant depletion of excitation energy for low
upconversion efficiency; however, preventing the incorporation of OH–into the crystal lattice …

Preparation of well-defined NaYF4 crystals with bright upconversion emission remains a
major challenge. The complicated chemical reactions as well as the effect of structure …

The phase evolution of as-prepared NaYF4: Yb, Er upconversion nanoparticles (UCNPs)
with a metastable cubic structure is studied based on in situ heating experiments via …

A series of hollow and luminescent capsules have been fabricated by covering luminescent
Gd2O3: Yb/Tm nanoparticles on the surface of uniform hollow mesoporous silica capsules …
