Review—Photoluminescence Spectroscopy of Mn2+-Activated Phosphors: Part II. Some Representative Phosphors

Abstract

The purpose of this review article, Part II, is to present the photoluminescence properties of Mn2+ ion in the intra-3d 5-shell electronic configuration activated in the various kinds of host materials. An analysis method presented in a separate article, Part I, are applied to the present Mn2+-activated phosphors. The characteristic photoluminescence (PL) properties for the Mn2+-activated phosphors are then discussed from a spectroscopic point of view. The phosphors considered herein can be classified into nine groups: (1) stoichiometric phosphor, (2) Mn2+-activated oxide phosphor, (3) Mn2+-activated phosphate phosphor, (4) Mn2+-activated nitride phosphor, (5) Mn2+-activated oxynitride phosphor, (6) Mn2+-activated chalcogenide phosphor, (7) Mn2+-activated halide phosphor, (8) Mn2+-activated organic−inorganic hybrid phosphor, and (9) Mn2+-activated multiple-site phosphor. The PL and PL excitation spectra are analyzed based on the theoretical modelling. Particularly, the effects of the lattice temperature on the PL intensity and luminescence lifetime are discussed in more detail. Key properties of the Mn2+-activated phosphors for use in a variety of device applications are also presented.
