A novel photocatalyst of Bi 3.64 Mo 0.36 O 6.55 doped with Tm 3+ /Yb 3+ was prepared by a simple coprecipitation method followed by a calcination technology. The as‐synthesized Tm 3+ /Yb 3+ ‐Bi 3.64 Mo 0.36 O 6.55 samples were characterized by various analytical methods. The as‐synthesized sample exhibited enhanced photocatalytic activity when degrading Rhodamine B under the irradiation of visible‐light. The photocatalytic degradation efficiency of Tm 3+ /Yb 3+ ‐Bi 3.64 Mo 0.36 O 6.55 (95.2%) was higher than that of pure Bi 3.64 Mo 0.36 O 6.55 (85.2%) in 50 min. Besides, the sample revealed a stable photocatalytic property after four photodegradation cycles. Therefore, this study may provide a better method to obtain stable upconversion photocatalyst degrading organic pollution with greatly improved activity.
