© 2014 IEEE. We demonstrate an optical method to evaluate the doping concentration, internal quantum efficiency (IQE) and non-radiative lifetime of semiconductor nanowires, through power dependent photoluminescence (PL) and time resolved PL (TRPL) measurement. Combining this method with standard PL and time resolved spectrum, we analyse the quality, band structure and doping distribution of Si doped InP nanowires. The doping result is correlated with electrical measurements of single nano wire device.
