Preparation and photoluminescence properties of nano-sized SrZnO2:Sm3+ phosphor powders obtained by high-energy ball milling

摘要

The SrZnO2:Sm3+ 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 D-5(4) excited states to H-6(J) ground states of Sm3+ ions. The crystallinity, morphology and particle size of SrZnO2:Sm3+ were different with different sintering temperatures. The luminescent intensity of SrZnO2:Sm3+ with different sintering temperatures was also investigated and reported. (C) 2014 Elsevier Ltd and Techna Group S.r.l. All rights reserved.
