  Near-infrared (NIR) luminescent materials have continuously received much attention, as they are promising for practical applications in controlling and processing light as active components in optical telecommunication systems, biomedicine, and light sources. Recently, new findings on the ultrabroadband NIR emission from novel Ni-doped and Bi-doped photonic materials are very attractive. Followed by the developed rare-earth doped photonic materials, Ni- and Bi-doped materials are of great interest in developing a new generation of tunable lasers and broadband optical amplifiers. Remarkable progress in the research of the novel metal ions doped photonic materials has been made over the last decade. The aim of this review is to present a general overview of the current state-of-the art in various Ni-doped and Bi-doped photonic materials, including the features, advantages and limitations of the materials as well as the future research trends.
