Lead halide perovskites exhibit unexceptionable photoelectric properties. However, these materials are unsatisfactory in terms of stability and toxicity. Herein, we report Rb₇Sb₃Cl₁₆ as a new kind of lead free perovskite variants. This material can be easily obtained through hydrothermal reactions. The composition is determined through structure refinement, elemental analysis and X-ray photoelectron spectra. Rb₇Sb₃Cl₁₆ exhibits a broad yellow emission at 560 nm, with a Stokes shift of 175 nm and a photoluminescence quantum yield (PLQY) around 26%. Rb₇Sb₃Cl₁₆ also shows good thermal and water stability due to its inorganic composition. White light-emitting diodes (LEDs) are constructed by combining Rb₇Sb₃Cl₁₆ as yellow phosphors, our previously reported Cs₂SnCl₆:2.75%Bi as blue phosphors, and commercial UV LED chips as the excitation source, producing a white light with the Commission Internationale de’Eclairage (CIE) color coordinates at (0.39, 0.38).

卤化铅钙钛矿表现出无可比拟的光电性能。然而，这些材料在稳定性和毒性方面并不令人满意。在此，我们将 Rb ₇ Sb ₃ Cl ₁₆报告为一种新型无铅钙钛矿变体。这种材料很容易通过水热反应得到。通过结构细化、元素分析和 X 射线光电子能谱确定其组成。Rb ₇ Sb ₃ Cl ₁₆在 560 nm 处呈现宽黄色发射，斯托克斯位移为 175 nm，光致发光量子产率 (PLQY) 约为 26%。Rb ₇ Sb ₃氯₁₆由于其无机成分，还显示出良好的热稳定性和水稳定性。白光发光二极管 (LED) 是通过将 Rb ₇ Sb ₃ Cl ₁₆作为黄色荧光粉、我们之前报道的 Cs ₂ SnCl ₆ :2.75%Bi 作为蓝色荧光粉以及商业 UV LED 芯片作为激发源而构建的，产生白色使用 Commission Internationale de'Eclairage (CIE) 颜色坐标 (0.39, 0.38) 的光。
