Preparation and photoluminescence properties of nano-sized SrZnO2:Sm3+ phosphor powders obtained by high-energy ball milling
Source abstract
Abstract
Abstract The SrZnO 2 :Sm 3+ nano-phosphors were synthesized by a high energy ball milling method. It was found that under ultraviolet excitation with a wavelength of 278 nm, the phosphor presented red luminescence that was attributed to the transitions from 5 D 4 excited states to 6 H J ground states of Sm 3+ ions. The crystallinity, morphology and particle size of SrZnO 2 :Sm 3+ were different with different sintering temperatures. The luminescent intensity of SrZnO 2 :Sm 3+ with different sintering temperatures was also investigated and reported.
