Abstract
Silica nanoparticles were used to develop a bluish-green emitting Ba2SiO4:Eu2+ phosphor, demonstrating their potential for white light applications. The phosphor showed a 48% enhancement of emission intensity compared to conventional silica-assisted phosphors. The use of silica nanoparticles as a precursor could lead to the creation of a more homogeneous distribution of cations and dopant ions. This uniform distribution could facilitate the proper infusion of dopants into the crystal host, resulting in improved emission. The phosphor exhibited high thermal stability, with 56% of its luminescence intensity maintained even at 190 °C compared to room temperature. To reduce thermal stress, a flexible remote phosphor has been developed successfully using optimized silica nanoparticles assisted Ba2SiO4:Eu2+ phosphor.
期刊介绍：
Frontiers of Optoelectronics seeks to provide a multidisciplinary forum for a broad mix of peer-reviewed academic papers in order to promote rapid communication and exchange between researchers in China and abroad. It introduces and reflects significant achievements being made in the field of photonics or optoelectronics. The topics include, but are not limited to, semiconductor optoelectronics, nano-photonics, information photonics, energy photonics, ultrafast photonics, biomedical photonics, nonlinear photonics, fiber optics, laser and terahertz technology and intelligent photonics. The journal publishes reviews, research articles, letters, comments, special issues and so on.
Frontiers of Optoelectronics especially encourages papers from new emerging and multidisciplinary areas, papers reflecting the international trends of research and development, and on special topics reporting progress made in the field of optoelectronics. All published papers will reflect the original thoughts of researchers and practitioners on basic theories, design and new technology in optoelectronics.
Frontiers of Optoelectronics is strictly peer-reviewed and only accepts original submissions in English. It is a fully OA journal and the APCs are covered by Higher Education Press and Huazhong University of Science and Technology.
● Presents the latest developments in optoelectronics and optics
