Figure 2From: Effects of crystallization and dopant concentration on the emission behavior of TiO2:Eu nanophosphorsThe size distribution histograms and corresponding Gaussian fits. (a) 0.0%, (b) 0.5%, (c) 1.0%, (d) 2.5% and (e) 5.0% (nominal) of the Eu dopant. Variation of the particle size with dopant concentration is shown in the bottom right. The average diameter decreased exponentially with the increasing molar concentration of Eu+3 ions.Back to article page
