A sublimation of ball-milled powders under ammonia flow was used to synthesize nitrogen-doped gallium phosphide nanobelts. The average width of the nanobelts is 300 nm and the thickness is 1/10 of the width. Photoluminescence showed the typical isoelectronic bound exciton peaks in the range of 2.11-2.25 eV, suggesting a concentration of ∼1018 cm-3 nitrogen atoms.
