Electrospinning preparation and high near-infrared temperature sensing performance of one-dimensional Y2Ti2O7:Cr3+/Yb3+ nano wire-embedded-tube structures with low Cr3+ concentrations

One-dimensional Y 2 Ti 2 O 7 :Cr 3+ /Yb 3+ nano wire-embedded tube structures with low Cr 3+ concentrations were fabricated via a simple single-nozzle electrospinning method. The structures have near-infrared emissions of 650–1100 nm and excellent temperature sensing properties.
