Abstract
In the pursuit of efficient up-conversion materials, praseodymium-doped yttrium orthosilicate (Y2SiO5:Pr3+) stands out, yet its potential is hindered by limited conversion efficiency. To overcome this challenge, we harness the power of plasmonic particles, which have the ability to amplify light in up-conversion nanomaterials. However, the ever-looming quenching effect threatens these enhancements. In our study, we introduce a novel approach by synthesizing hollow shell Y2SiO5-coated particles with precise control over shell thickness. This innovation not only boosts photoluminescence intensity but also serves as a protective barrier, preventing quenching effects by isolating plasmonic particles from up-conversion nanoparticles. Our results reveal that this strategic synergy, combining Y2SiO5 with AgAu3@SiO2 nanoparticles, promises a substantial increase in efficiency. By effectively nullifying quenching effects and maintaining optimal SiO2 content, this approach marks a significant stride in enhancing Y2SiO5 up-conversion efficiency through the integration of plasmonic materials.
