The chapter discussed the luminescence properties of perovskite titanate phosphor materials for various phosphor applications. The existing crystal structure of perovskite titanate materials is in the form of ABO3, which have incredible and diverse properties. The incorporation of rare-earth (RE) ions, as well as efficient energy transfer from host to RE ions and between RE ions, can improve the luminescence dynamics of perovskite titanate phosphors. Perovskite titanates’ unique properties, such as their relatively high thermal and chemical stability, low phonon energy, prominent physical properties and non-toxicity, make them an intriguing material to investigate further in various luminescence applications, particularly in harsh conditions, especially when doped with various RE ions for various nanoscale devices. The luminescence properties of RE ions and transition metals (TMs) incorporated into perovskite CaTiO3 and ZnTiO3 materials, as well as the role of efficient energy transfer, were also discussed. This chapter reports on the experimental work for both pure, RE ions and TMs doped CaTiO3 and ZnTiO3 phosphor materials as down- and up-converting materials. The advantages of enhancing the luminescence dynamics of CaTiO3 and ZnTiO3 phosphor materials have been discussed.
