Effects of Sintering Temperature on the Morphology and Photoluminescence of Eu³⁺ Doped Zinc Molybdenum Oxide Hydrate

Figure 6

CIE chromaticity diagram of the colored PL from the precursors after thermal annealing at 200°C (a), 400°C (b), 600°C (c), and 800°C (d). The luminescent materials in (a) are Eu³⁺ doped Zn₅Mo₂O₁₁·5H₂O whilst those in (b–d) are Eu³⁺ doped ZnMoO₄ compounds.
