摘要：In this study, a series of Ca9Sc(PO4)7: Sm3+ (CSP: Sm3+) orange-red phosphors were synthesized by the conventional solid-phase method, and their crystal structure, luminescent properties, decay lifetimes and thermal stability were investigated. The computational result shows that the CSP substrate has a wide band gap value (4.258?eV). At 403?nm excitation, the emission spectrum of CSP: Sm3+ phosphors has an intense orange red emission at 602?nm. The optimum concentration of Sm3+ ion doped phosphor is 0.12, and the phosphor has a high color purity (97%). Moreover, the prepared phosphors have excellent thermal stability, and the emission intensity can still reach 91.68% of that at room temperature at 423?K. The above results indicate that the prepared CSP: Sm3+ phosphors have excellent luminescent properties and have potential applications in solid-state lighting. ? 2024, The Author(s), under exclusive licence to Springer-Verlag GmbH, DE part of Springer Nature.
