摘要：

Fe3O4@SiO2 nanoparticles were used as scatters in Rhodamine B solutions, and coherent random lasing was achieved. It was revealed that Fe3O4@SiO2 doped dye solution has a magnetically controllable feature. When external magnetic field is applied, the laser peaks would disappear if the diameter of Fe3O4 is relatively large (similar to 100 nm), while the laser peaks would exist if the diameter of Fe3O4 is relatively small (similar to 12 nm). This kind of random laser may has potential applications in fabricating magnetic sensors and integrated optical device. (C) 2014 Elsevier B.V. All rights reserved.
