Abstract: Here we have studied a novel scattering medium for random laser. This medium is composed of TiO2@Silica nanoparticles suspended in an ethanol solution of rhodamine 6G. TiO2 nanoparticles with average diameter of 0.41 μm were coated with a silica shell of ~40 nm thickness. Random laser study comparing TiO2 and TiO2@Silica nanoparticles suspended in ethanol solution of rhodamine 6G was performed. The study showed a high efficiency, low threshold, narrower bandwidth and lower photodegradation for TiO2@Silica system. Optical and chemical stability has been combined by coating TiO2 nanoparticles with a silica shell of ~40nm thickness.
