Abstract

Optical fiber with YPO:Pr nanocrystals (NCs) is presented for the first time using the glass powder-NCs doping method. The method's advantage is separate preparation of NCs and glass to preserve luminescent and optical properties of NCs once they are incorporated into optical fiber. The YPO:Pr nanocrystals were synthesized by the co-precipitation and hydrothermal methods, optimized for size (< 100 nm), shape, Pr ions concentration (0.2 mol%), and emission lifetime. The core glass was selected from the non-silica PO-containing system with refractive index (n = 1.788) close to the NCs (n = 1.657, n = 1.838). Optical fiber was drawn by modified powder-in-tube method after pre-sintering of glass powder-YPO:Pr (wt 3%) mixture to form optical fiber preform. Luminescent properties of YPO:Pr and optical fiber showed their excellent agreement, including sharp Pr emission at 600 nm (D-H) and D level lifetime (τ = 156 ± 5 µs) under 488 nm excitation. The distribution of the YPO:Pr NCs in optical fiber were analyzed by TEM-EDS in the core region (FIB-SEM-prepared). The successful usage of glass powder-NCs doping method was discussed in the aspect of promising properties of the first YPO:Pr doped optical fiber as a new way to develop active materials for lasing applications, among others.

摘要

首次采用玻璃粉末 - 纳米晶体掺杂法制备了含有YPO:Pr纳米晶体（NCs）的光纤。该方法的优点是将纳米晶体和玻璃分开制备，以便在将纳米晶体掺入光纤后保持其发光和光学特性。通过共沉淀和水热法合成了YPO:Pr纳米晶体，并对其尺寸（<100 nm）、形状、Pr离子浓度（0.2 mol%）和发射寿命进行了优化。核心玻璃选自非二氧化硅含磷系统，其折射率（n = 1.788）接近纳米晶体的折射率（n = 1.657，n = 1.838）。在对玻璃粉末 - YPO:Pr（重量比3%）混合物进行预烧结以形成光纤预制棒后，采用改进的管中粉末法拉制光纤。YPO:Pr和光纤的发光特性显示出良好的一致性，包括在488 nm激发下600 nm处（D - H）的尖锐Pr发射和D能级寿命（τ = 156 ± 5 μs）。通过TEM - EDS对核心区域（通过聚焦离子束扫描电子显微镜制备）的光纤中YPO:Pr纳米晶体的分布进行了分析。从首个YPO:Pr掺杂光纤作为开发激光应用活性材料的新途径等具有前景的特性方面，讨论了玻璃粉末 - 纳米晶体掺杂法的成功应用。
