Figure 3

(Color online) Room temperature photoluminescence (black circles) and optical absorption (inset) spectra of ZnO spherical nanoparticles prepared from (a) the regular solvent OD; (b) the mixture of TOA and OD in 1:10 molar ratio; (c) the mixture of TOPO and OD in 1:12 molar ratio. The PL spectra were fitted by Gaussian functions (shown as red solid line and green dotted lines)
