摘要

在 30% 的环境湿度下，通过单喷嘴电纺丝制备了一维（1D）Y3Ga5O12:Pr3+ 纳米管（YGG:Pr3+ NTs）。YGG:Pr3+ 纳米管的外径在 190 至 210 nm 之间，管壁厚度为 35-45 nm。纳米管由单晶 YGG:Pr3+ 纳米颗粒组成。研究了不同 Pr3+ 浓度的 YGG:Pr3+ 纳米管的光学特性，尤其是它们的温度敏感特性。在 303-453 K 的温度范围内，YGG: 0.5% Pr3+ NTs 的灵敏度最高，约为 7.90 × 10-3 K-1。

Preparation of Y3Ga5O12:Pr3+ nanotubes with a single-crystal structure via single-nozzle electrospinning for temperature sensing applications†

One-dimensional (1D) Y₃Ga₅O₁₂:Pr³⁺ nanotubes (YGG:Pr³⁺ NTs) were prepared via single-nozzle electrospinning at 30% ambient humidity. The outer diameters of the YGG:Pr³⁺ NTs are between 190 and 210 nm, and the wall thickness is 35–45 nm. The nanotube consists of single-crystal YGG:Pr³⁺ nanoparticles. The optical properties of YGG:Pr³⁺ NTs with different Pr³⁺ concentrations, particularly their temperature-sensitive properties, were investigated. The YGG: 0.5% Pr³⁺ NTs exhibit the highest sensitivity of approximately 7.90 × 10⁻³ K⁻¹ within the temperature range of 303–453 K.
