A tunable blue random laser based on solid waveguide gain films with silver nanoparticles (NPs) and SiO2 NPs is demonstrated. Localized surface plasmon resonance (LSPR) property and multiple scattering are proven playing an important role simultaneously. The tunability of the blue random laser is realized by simply roughing and changing the thickness of the solid waveguide gain films. To our knowledge, it is the first time using this method to achieve a wide wavelength tuning range of similar to 24 nm. (C) 2019 Elsevier B.V. All rights reserved.
