Description Recently, carbon-phosphide (C-P) polymers are coming to scene. They can be synthesized e.g. via plasma deposition from CH4 and PH3 gas mixture.1 The C-P polymer found already application in optoelectronics2 and C-P nano-composites in lithium and sodium batteries.3, 4 In this work, we studied the generation of carbon-phosphide CmPn±clusters via laser ablation of several nano-composites of nanodiamonds (ND) or graphene (G), with red or black phosphorus (RP or BP) or phosphorene: ND-phosphorene, ND-RP, ND-BP, G-RP, G-BP, etc.) using pulsed laser (337 nm) in a mass spectrometer as a kind of synthesizer. All nano-composites used in the study were characterized by electron microscopy. Phosphorene was prepared by liquid exfoliation from black phosphorus in N-methyl-2-pyrrolidone solvent using ultrasonication.5 We demonstrated generation of several series of CmPn+ cluster ions: CmP+ (m=3–47), CmP2+ (m=2–44), CmP3+ (m=1–42), CmP4+ (m=1–39), CmP5+ (m=1–37), CmP6+ (m=1–34), CmP7+ (m=1–31), CmP8+ (m=1–29), CmP9+ (m=1–26), CmP10+ (m=1–24), CmP11+ (m=1–21), and CmP12+ (m=1–19) clusters were detected. LDI of nanodiamond composites with red/black phosphorus or with phosphorene yielded C24P5+2n+ (n=0–28), C24P5+2n+ (n=0–16), and C24P5+2n+ (n=0–14), respectively. Dominant clusters with the highest intensities were C7P+, C6P3+, C10P3+, and C13P5+, while graphene was evaluated as the most suitable precursor for C-P clusters generation. The results of this work were recently published.6
