The effect of ultrasonic vibrations on the self-assembly and phase separation of nanorods and nanospheres is investigated. Such deposits of rod-sphere mixture on SiO2 surface, dried during ultrasonic vibrations, are compared with static nanoparticle deposits. Phaseseparation at various positions of the coffee-stain ring for both of the cases is evaluated. The ensuing phase separation under ultrasonic agitation is found more noticeable than the one ensemble through static drying. Also, shape separated nanoparticle deposits are studied at various positions of the coffee-stain ring and discuss in relation with steric interaction.
