This paper reports on the growth and spectroscopic properties of Er 3+ /Yb 3+ :NaGd(MoO 4 ) 2 and Ce 3+ /Er 3+ /Yb 3+ :NaGd(MoO 4 ) 2 crystals. Er 3+ /Yb 3+ :NaGd(MoO 4 ) 2 and Ce 3+ /Er 3+ /Yb 3+ :NaGd(MoO 4 ) 2 crystals were grown by the Czochralski method. The investigated polarized spectroscopic properties of both crystals revealed that when the Ce 3+ ion was introduced into Ce 3+ /Er 3+ /Yb 3+ :NaGd(MoO 4 ) 2 crystal, it could enhance the 1.5 µm fluorescence intensity and decrease the fluorescence lifetime of Ce 3+ /Er 3+ /Yb 3+ :NaGd(MoO4) 2 crystal. To sum up the spectral properties of Ce 3+ /Er 3+ /Yb 3+ :NaGd(MoO4) 2 crystal, it may be regarded as a potential 1.5 µm Er 3+ laser crystal material.
