Near UV-Blue Excitable Green-Emitting Nanocrystalline Oxide
Figure 1
(a) XRD patterns of the as-synthesized red-emitting phosphor powders produced by the PACS method. Principal peaks are labeled and correspond to the crystalline phases: (α) α-Al2O3 (JCPDS #50-1496), (γ) γ-Al2O3 (JCPDS #10-0425), (*) AlOOH (JCPDS #21-1307). Peaks of the 10.0 at % Eu-doped sample are labeled with “m” (JCPDS #72-0683). Below, (b) XRD patterns of the green-emitting phosphor powders produced after RIRO. Principal peaks are labeled and correspond to the crystalline phases: (α) α-Al2O3 (JCPDS #50-1496) and (δ) δ-Al2O3 (JCPDS #46-1131). The principal planes of the orthorombic EuAlO3 (JCPDS #09-0084) phase are indexed in both cases.
