We present a procedure to produce single-phase PdP nanocrystals (NCs). The approach involves the reaction of palladium(II) acetylacetonate and hexamethylphosphoroustriamide to nucleate defective Pd P nanoparticles that subsequently, with further phosphorous incorporation, crystallize into PdP .

A cost-effective and scalable approach was developed to produce monodisperse NiCoP nanocrystals (NCs) with composition tuned over the entire range (0 ≤ x ≤ 2). NiCoP NCs were synthesized using low-cost, stable and low-toxicity triphenyl phosphite (TPP) as a phosphorus source, metal chlorides as metal precursors and hexadecylamine (HDA) as a ligand. [...]

Monodisperse CuZnSnS (CZTS) nanocrystals (NCs), with quasi-spherical shape, were prepared by a facile, high-yield, scalable, and high-concentration heat-up procedure. The key parameters to minimize the NC size distribution were efficient mixing and heat transfer in the reaction mixture through intensive argon bubbling and improved control of the heating ramp stability.
