Abstract

In this paper, the impurity influences of BNNTs on photoluminescence (PL) analysis have been investigated systematically. Similar PL spectra were obtained from bulk disk of the cold-pressed BNNTs and dispersed individual BNNTs deposited on CaF2 substrate. Metal impurities such as Fe and Au do not affect PL emissions of the BNNTs strongly possibly because Au doping creates sever structural damages but do not change the electronic structure.
