Abstract

Under 980 nm excitation, upconversion (UC) emissions in the UV range of 270-320 nm were observed in nanocrystals Y_0.795-xGd _xYb_0.2Tm_0.005F₃ (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 ⁶I_J, ⁶P_J→⁸S_7/2 (Gd³⁺), and ³P₀/¹I₆ → ³H₆ (Tm³⁺). The energy transfer from Tm ³⁺ 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.
