Abstract

Pure and Pr-doped BaYF nanoparticles were synthesized by the microwave hydrothermal method. The nanoparticles were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), and optical spectroscopy. The XRD and TEM confirm that the average size of nanoparticles is in the range of 26-37 nm. The optical excitation and luminescence spectra of BaYF:Pr nanoparticles are presented in the visible and ultraviolet (UV) range. It has been verified that Pr ions are capable of emitting UV-C photons when excited by a 444 nm laser. This emission arises from a two-photon energy-transfer upconversion mechanism. The concentration dependence of the upconversion luminescence of BaYF:Pr was studied.

摘要

采用微波水热法合成了纯的和掺Pr的BaYF纳米颗粒。通过X射线衍射（XRD）、透射电子显微镜（TEM）和光谱对纳米颗粒进行了表征。XRD和TEM证实纳米颗粒的平均尺寸在26 - 37 nm范围内。给出了BaYF:Pr纳米颗粒在可见光和紫外（UV）范围内的光激发和发光光谱。已经证实，当用444 nm激光激发时，Pr离子能够发射UV - C光子。这种发射源于双光子能量转移上转换机制。研究了BaYF:Pr上转换发光的浓度依赖性。
