In this study, a limited-flow of argon gas was employed to grow Ce3+:YAG single crystal by Czochralski (CZ) technique. Without any reduction gas, the reduction of Ce4+ to Ce3+ can be managed and the formation of Ce3+ ions is achievable by this method. The X-ray diffraction (XRD) analysis, absorption and photoluminescence spectroscopy were used to study the structural and optical properties of the grown crystal. The synthesized crystal has strong emission at 527 nm. No colorcenter absorption and emission bands were observed in as-grown Ce:YAG crystal and it is free of usual luminescence crystalline defects..
