The design, synthesis, and study of lanthanide coordination compounds with luminescent magnetic properties attractive in modern technologies is still a pressing challenging task. In the present work, series tetrakis-carbacylamidophosphate PPh4[LnL4] (where HL = diphenyl-N-benzoylamidophosphate) several ions such as NdIII, SmIII, DyIII, TmIII was prepared studied by X-ray analysis luminescence spectroscopy at 293 77 K, well measurements. Coordination are not isostructural, but type same. All them have intense sensitized emission. PPh4[SmL4], PPh4[DyL4], PPh4[TmL4] chelates characterized dual visible infrared emission mechanoluminescence. addition, PPh4[DyL4] has multifunctional Vis NIR emissions, brilliant mechanoluminescence single-ion molecular magnet (SIM) properties. This compound holds great promise radiation converters.
