Thin-Film Electroluminescent Devices Fabricated Using La_2O_3-Based Multi-component Oxide Phosphors

摘要

Multicolor PL and EL emissions were observed from newly developed La_2O_3-based oxide phosphors using BaLa_2O_4, CaLa_2O_4 or SrLa_2O_4 as the host material. The use of Bi-activated oxide phosphors co-doped with Eu made it possible to control the EL and PL emission color over a wide range.
