Efficient multicolor X-ray excited persistent luminescence enabled by Gd-mediated trap clusters.

ABSTRACT: Persistent luminescence materials are promising for night-vision displays, background-free medical diagnostics, and high-resolution radiography, yet achieving efficient violet, yellow, and red emission within a single robust and scalable host remains a longstanding challenging. Here, we overcame this limitation by constructing Gd³⁺-mediated cluster traps within alkaline-earth fluorochlorides to minimize energy loss during electron migration. These clusters serve as both intrinsic emitters and efficient energy transfer platforms for various activators, including Eu²⁺, Sm²⁺, Tb³⁺, and Mn²⁺, enabling bright and spectrally tunable multicolor persistent luminescence upon X-ray irradiation. The persistent luminescence intensity of Eu^2+<
