Effect of irradiation time on characteristics of Gd2O3:Er,Yb NPs by laser ablation in liquid

Up-conversion Gd 2 O 3 :Er,Yb nanoparticles (NPs) were fabricated by laser ablation in liquid, and the effect of laser irradiation time on their characteristics was investigated. The light source (a focused 532 nm second harmonic laser beam generated from a Nd:YAG laser) was used to irradiate the ta...

Zusammenfassung:	Up-conversion Gd 2 O 3 :Er,Yb nanoparticles (NPs) were fabricated by laser ablation in liquid, and the effect of laser irradiation time on their characteristics was investigated. The light source (a focused 532 nm second harmonic laser beam generated from a Nd:YAG laser) was used to irradiate the target pellet in water for 5, 15, or 30 min. Coarse NPs (> 200 nm) and fine NPs (
