Fabrication of Er 3+ :YAlO 3 fibers by electrospinning method for upconversion luminescence applications
Source abstract
Abstract
Abstract This study aimed to prepare YAlO 3 fibers doped with 2 mol% Er 3+ using electrospinning and a carbon‐free sol system as the precursor. X‐ray diffraction, thermal gravimetry and differential thermal analysis, and Fourier transform infrared were employed to characterize the thermal behavior and crystallization process of the precursor fibers. Scanning electron microscope analysis showed that the Er 3+ :YAlO 3 fibers had a uniform diameter of 1 μm, a dense and crack‐free surface, and a non‐porous cross‐section. Upon excitation at 450 and 488 nm, upconverted luminescence spectra were obtained from the Er 3+ :YAlO 3 fibers. This observation indicates their potential as upconversion luminescent agents capable of converting visible light into ultraviolet light. These properties make the Er 3+ :YAlO 3 fibers promising candidates for various upconversion luminescence applications.
