Luminescent materials have played a vital role in human society, with phosphor-converted light-emitting diodes (pc-LEDs) representing the cutting-edge in lighting solutions. As societal demands for improved material quality continue to rise, the quest for materials with enhanced performance has become paramount. Eu2+/Ce3+-activated inorganic luminescent materials have garnered significant attention due to their high luminescence efficiency and tunable properties. Recent research has focused on developing Eu2+/Ce3+-activated inorganic luminescent materials with anti-/zero thermal quenching behavior, leveraging the benefits of host structures and activator ions. To facilitate their commercial viability, a comprehensive understanding of their properties, mechanisms, and current status is essential. This study delves into the luminescence mechanisms of Eu2+/Ce3+ activator ions, provides a detailed analysis of the typical thermal behaviors of Eu2+/Ce3+-activated inorganic phosphors, outlines strategies for enhancing thermal stability from both intrinsic and extrinsic perspectives, and categorizes the reported instances of anti-/zero thermal quenching in Eu2+/Ce3+-activated phosphors. Lastly, drawing on the present landscape, this paper offers insights into the future development and prospects of similar phosphors, aiming to serve as a valuable reference for the advancement of Eu2+/Ce3+-activated inorganic luminescent materials.
