Synthesis and Characterization of Highly Crystalline Zinc Phosphide Nanoparticles

Abstract:

Nanoscale alpha zinc phosphide (α-Zn₃P₂) particles are a class of promising opto-electronic materials which have attracted worldwide attention. The synthetic protocols pertaining to α-Zn₃P₂ nanoparticles have been largely based on the use of costly, pyrophoric and toxic phosphines precursors. We reported here the results of our investigation into the viability of fabricating crystalline α-Zn₃P₂ nanoparticles using phosphorous pentabromide (PBr₅) as precursor via an air-stable solid hydrogen phosphide (PH)_x intermediate. HRTEM analysis revealed the best sample as spherical crystalline α-Zn₃P₂ nanoparticles with diameter found to be 5.8±2.1 nm. These particles exhibited photoluminescence centered at 470 nm (2.6 eV), blue-shifted by 1.2 eV from the 1.4 eV of bulk α-Zn₃P₂.
