Abstract

The very first single-sized CdP H-V nanoparticles were synthesized via a non-injection-based approach which was designed to be thermodynamically driven. The CdP nanoparticles were synthesized in a pure form and exhibited bright bandgap photoemission peaking at 455 nm with a full width at half-maximum (fwhm) of only 17 nm and narrow bandgap absorption peaking at 451 nm. Compared to those reported before with a fwhm of 50-150 nm, the newly developed CdP nanoparticles represent significant progress in synthesis with better design and control. Cadmium acetate dihydrate (Cd(OAc)·2HO) and tris(trimetliylsilyl)phosphine ((TMS)3P) were used as Cd and P source compounds, respectively; the synthesis was carried out in 1-octadecene (ODE), a noncoordinating solvent. The novel CdP nanoparticles were further characterized by transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDX), powder X-ray diffraction (PXRD), and Cd and P solid-state NMR. These single-sized Cd P nanoparticles are the first example of class II-V magic-sized nanoparticles (MSNs).
