Abstract

This manuscript presents a study on the growth stress of Al₂O₃ nanocrystals in Lu₂O₃ matrix and its resultant effect on the optical properties of Al₂O₃ nanocrystals. The high-resolution transmission electron microscopy study reveals the complete isolation of Al₂O₃ nanocrystals embedded in Lu₂O₃ matrix. Two dimensional finite element calculations clearly demonstrate that Al₂O₃ nanocrystals certainly experience great compressive stress in Lu₂O₃ matrix. This may lead to a great deal of defects formed around or inside Al₂O₃ nanocrystals to relax the compressive stress incurred by Al₂O₃ nanocrystals, leading to the photoluminescence emission observed.
