Fig. 1

a Optical image of bulk powders revealing the color progression that occurs during increased milling time via high-energy ball milling; the transition from red to brown to black is a direct result of the mixture of amorphous RP and crystalline BP present (scale bar is 1 cm). b Powder x-ray diffraction (XRD) patterns of RP during conversion to BP showing an increase in the intensity of the main BP (040) and (111) peaks with increasing milling time; here, all patterns vertically offset correspond to runs at a constant speed 600 rpm, black bars are BP (PDF 03-065-2491), and silicon standard peaks are marked.
