Rare-earths doped-nanoparticles prepared by pulsed laser ablation in liquids

Abstract

This feature article highlights the recent advances on the lanthanide-activated nanoparticles prepared by pulsed laser ablation in liquids (PLAL). In the past decade, rare-earths-activated nanoparticles have been recognized from various applications including lots of high-tech products, green technologies, bioimaging and medical utilization. To obtain inorganic nanoparticles with different morphologies and sizes, pulsed laser ablation in liquids is a green and versatile technique. In this paper, a survey of the nanoparticle's formation during the laser ablation in the liquids is first introduced. We focus on the control of the size and morphology through proper laser parameters, choice of the reaction solution and proper surfactants. In the last part of the paper, we successfully prepared persistent luminescent SrAl2O4: Eu2+, Dy3+ by laser ablation in liquids and their optical features are investigated.
