Abstract

We successfully synthesized Er³⁺/Yb³⁺ co-doped KY₃F₁₀ nanocrystals by a facile hydrothermal method. The average size of the as-prepared nanocrystals was about 60 nm based on the observation of scanning electron microscope. Under the excitation of a 976 nm laser, the Er³⁺/Yb³⁺ doped KY₃F₁₀ nanocrystals showed intense near-infrared emission band centered at 1539 nm. The optimal concentrations of Er³⁺ were carefully selected according to the quantum yield measurement for a stronger emission in the C-band. The as-prepared nanocrystals were dispersed into a monomer, bisphenol A ethoxylate diacrylates, in which self-written waveguides can be fabricated under the irradiation of an induced laser at 450 nm. The KY₃F₁₀: Er³⁺/Yb³⁺ nanocrystals embedded polymer waveguide were fabricated by laser-induced self-written technique. Two pieces of single mode fiber were well connected with the waveguide in the fabrication procedure. Under a 976 nm laser pumping, amplified spontaneous emission at 1539 nm was observed in the KY₃F₁₀: Er³⁺/Yb³⁺ nanocrystals doped waveguide.
