Biosynthesized zinc oxide and titanium dioxide nanoparticles by aloe vera extract for tunable Q-switched application

Zinc oxide (ZnO) and titanium dioxide (TiO2) nanoparticles (NPs) were biosynthesized by using aloe vera extract for tunable Q-switched application. ZnO TiO2 NPs was then prepared as a saturable absorber (SA) via mechanical exfoliation technique. By measuring nonlinear optical absorption, the modulat...
