Particle Size Control of Y2O3:Eu3+ Prepared via a Coconut Water-Assisted Sol-Gel Method

Figure 4

Micrographs of Y2O3:Eu3+ produced by proteic sol-gel: (a) without pH control and calcined at 850°C and (b) at pH = 7.0 and calcined at 350°C. The images were registered during illumination with UV light.
