Abstract

Abstract: Electrospinning is the most favourable method for production of polymer nanofibres. In this study, we prepared a samarium β‐diketonate complex that incorporated pure, surface‐roughened and coaxial hollow poly(methylmethacrylate) (PMMA) nanofibres through electrospinning. The successful incorporation of this samarium complex into the PMMA nanofibres with different architectures was elucidated through various structural and morphological studies. Optical investigations as well as other characterization techniques for the pure, surface‐roughened and coaxial hollow PMMA nanofibres before and after incorporating the samarium β‐diketonate complex explained the host matrix nature of the PMMA nanofibres. Photoluminescence properties of the pure and structurally modified PMMA nanofibres were enhanced two or three times after incorporating the samarium complex into the fibre. Comparison of the optical properties between the pure and structurally modified PMMA nanofibres incorporating the samarium β‐diketonate complex demonstrated the structural and optical improvements as well as the better host matrix nature of the surface‐roughened and coaxial hollow PMMA nanofibres over pure PMMA nanofibres for the samarium β‐diketonate complex. These optical enhancements make these materials applicable for various optical devices. Abstract : Pure, surface‐roughened and coaxial hollow electrospun PMMA nanofibres incorporated with a synthesized samarium β‐diketonate complex were prepared. The samarium complex caused a blue shift in the photoluminescence peaks of these PMMA fibre samples. Photoluminescence intensity of all the PMMA fibre samples was enhanced after incorporating the samarium complex.
