The development of environmentally friendly full‐inorganic luminescent materials with tunable emission properties and exceptional thermal stability is of paramount importance for applications in optoelectronic devices, solid‐state lighting, and anti‐counterfeiting technologies. In this study, a novel luminescent crystal based on calcium perovskites Cs2CaCl4·2H2O (CCCH) are explored using a hydrothermal method. Simultaneous co‐doping of CCCH with Sn2+ and Mn2+ yields the s‐p transition‐induced cyan light from Sn2+ and d‐d transition‐induced yellow light from Mn2+. It demonstrates effective energy transfer from self‐trapped exciton (STE) of matrix CCCH and s‐p transition of Sn2+ to Mn2+, synergizing composite white lights with tunable colors. Furthermore, the incorporation of Sn2+ into CCCH introduces a red shift from blue to cyan emission with a remarkable enhancement in luminescent intensity by a factor of 12 times. The crystal orbital Hamiltonian populations (─COHP) calculations revealed the crucial role of Mn2+ in lattice stability, as evidenced by the decomposition temperature exceeding 305 °C for CCCH:Sn2+,Mn2+ whereas 210 °C for undoped CCCH matrix. This research provides a comprehensive investigation of the luminescent properties of CCCH:Sn2+,Mn2+ crystal, holding significant promise for practical technological advancements in lighting and anti‐counterfeiting technologies.

The development of efficient, stable, and cost‐effective luminescent materials is crucial for advancing lighting and display technologies. In this study, a series of tunable luminescent materials based on the novel 0D all‐inorganic perovskite (AIP) crystal Rb₃ZnBr₅ (RZB) is obtained. The emission of Sn2⁺ doped RZB spans the entire visible light range and extends into the near‐infrared (NIR) region, achieving a photoluminescence quantum yield (PLQY) of 75%. The distinct lifetimes combined with theoretical calculations, indicate that the broadband dual‐peak emissions at 496 and 636 nm originate from the singlet and triplet states of Sn2⁺, respectively, which is rarely observed in Sn2⁺‐doped perovskite crystals. The phosphor RZB:Sn2⁺ demonstrates the high thermal stability, along with excellent moisture and air stability. Co‐doping RZB with Sn2⁺ and Mn2⁺ broadens the excitation spectrum and allows precise control over the excitation wavelength, facilitating dynamic transitions from warm white to yellow and green light. This feature is particularly beneficial for multicolor LEDs and multi‐level anti‐counterfeiting applications.
