Abstract

A series of GdOCl:Yb, Tm one-dimensional nanostructures with dual-mode [down-conversion (DC) and up-conversion (UC)] luminescence were successfully fabricated by electrospinning technique incorporated with double-crucible chlorination method. The samples have single-phase tetragonal structure with space group of P4/nmm. The diameter and width of GdOCl:10%Yb, 0.1%Tm nanofibers and nanobelts are 212.84 ± 1.04 nm and 1.07 ± 0.03 μm, respectively. Excited by 357-nm ultraviolet (UV) light and 980-nm near-infrared (NIR) light, Yb and Tm ions co-doped GdOCl nanostructures exhibit bright blue emission. The mechanism of UC emission is determined to be three-photon process. The energy transfer processes from Yb to Tm are discussed in detail. Moreover, the as-obtained products possess paramagnetic properties at ambient temperature. The type of difunctional one-dimensional nanomaterials has promising applications in anti-counterfeiting, drug delivery, solid state lasers, biolabels and light emitting diodes (LEDs).
