Abstract
The synthesis of pure and rare-earth doped gallium oxide (β-Ga2O3) nanoparticles is reported. The synthesized nanoparticles are characterized with XRD, TEM, and PL analyses. Strong blue emission is observed from un-doped gallium oxide nanoparticles, while nanoparticles doped with Eu3+ and Tb3+ give strong red and green emissions, respectively. When doped with Eu3+ and Tb3+ together, gallium oxide nanoparticles emit white light. The CIE co-ordinate of the emitted light was found to be (0.33, 0.33), which is well within the white light region.
