The ways to improve the energy conversion efficiency in erbium-doped Gd 2 O 3 nanoparticles

Abstract

The basic requirements for the crystal lattice and defectiveness of Gd 2 O 3 matrix as well as for the concentration of Er 3+ dopants to achieve the enhanced parameters of energy conversion in Gd 2 O 3 :Er nanoparticles are summarized. The obtained data allow to optimize and improve the functional characteristics of Gd 2 O 3 :Er-based down-conversion layers applying in solar cells. © 2018 Institute of Physics Publishing.
