Upconversion Luminescent Properties of YVO₄:Tm³⁺, Ho³⁺, Yb³⁺

Abstract:

YVO₄ co-doped with Tm³⁺/Ho³⁺/Yb³⁺ were synthesized by the high temperature solid state method and the optical properties of phosphors were characterized. Intense visible emissions centered at around 475, 541 and 649 nm, originated from the transitions of Tm³⁺:¹G₄→³H₆, Ho³:⁵S₂/>:⁵F₄ →⁵I₈, Tm³⁺:⁵G₄→3F₄ and Ho³⁺:⁵F₅→⁵I₈, respectively, have been observed in samples upon excitation with a 980 nm laser diode, and the involved mechanisms have been explained.
