Abstract

Under 980nm excitation, upconversion (UC) emissions in the UV range of 270320nm were observed in nanocrystals Y0.795xGdxYb0.2Tm0.005F3 (x=0, 0.1, 0.2, 0.5, and 0.795), which were synthesized through a hydrothermal method. These UC emissions can be assigned to the transitions of IJ6, PJ6S728 (Gd3+), and P03I61H63 (Tm3+). The energy transfer from Tm3+ to Gd3+ plays a crucial role in populating the excited states of Gd3+. The shortest wavelength of upconverted emission converted from the infrared region was demonstrated here.
