Xiangeng Meng, Koji Fujita, Yusuke Moriguchi, Yanhua Zong and Katsuhisa Tanaka Metal–Dielectric Core–Shell Nanoparticles: Advanced Plasmonic Architectures Towards Multiple Control of Random Lasers Advanced Optical Materials 1
A plasmonic approach to control figures of merit for a random laser is developed. Using gold–silica core–shell nanoparticles, the coupling between the metal and fluorophores can be tailored with the shell thickness. As a result, random lasing properties such as lasing spikiness, pump threshold, and mode interactions can be manipulated.
