Figure 4From: Enhancing blue luminescence from Ce-doped ZnO nanophosphor by Li dopingPL spectra of samples. (a) PL spectra of Ce0.004Zn0.996 - xO:x Li+ with x = 0 (i), x = 0.005 (ii), x = 0.01 (iii), x = 0.02 (iv), and x = 0.04 (v). (b), (c), (d), and (e) are the corresponding Gaussian curve fits for the spectra i, ii, iii, and iv in (a).Back to article page
