Effect of Ag NPs: Ultrasonics Attenuation Properties

Abstract:

Silver nanoparticles (Ag NPs) are embedded in Er³⁺/Nd³⁺ co-doped lithium niobate tellurite glasses of the form (68-x)TeO₂-15Li₂CO₃-15Nb₂O₅-1Er₂O₃-1Nd₂O₃-(x)AgCl with x = 1,2 and 3 mol% via conventional melt-quenching technique. The ultrasonic attenuation shows the rate of sound energy reduction when an ultrasonic wave is propagating in a medium which is the lithium niobate tellurite glasses. The glass attenuation depends on the grain size, viscous friction, crystal structure, porosity and hardness. The existence of Ag NPs with an average size of 3.7 nm is confirmed using TEM analysis.
