Abstract

Influence of post heat treatment on particulate, structural, surface, and optical properties of YAG:Yb³⁺ nanoparticles prepared by glycothermal method is studied to understand factors for determining photoluminescence intensity. Characterization is performed on electron microscopy, X-ray diffractometry, infrared absorption spectroscopy, and optical measurements. Near infrared emission under 940 nm near infrared excitation is observed at 1029 nm corresponding to ²F_5/2→²F_7/2 transition of Yb³⁺. Subsequent heat treatment causes crystallite growth and elimination of hydroxyl groups, resulting in an enhancement of the near infrared emission.
