Abstract ： A novel method of codoping the Er3+ , Yb3+ , and Ho3+ ions in tellurite glasses is demonstrated to obtain a high efficiency of infrared-to-visible upconversion. Three intense emission bands observed in Er3+ , Yb3+ , and Ho3+ codoped tellurite glasses centred at 525, 547, and 657nm correspond to Er3+ : 2 H11/2 → 4 I15/2 , Er3+ : 4 S3/2 → 4 I15/2 +Ho3+ : 5 S2 (5 F4 ) → 5 I8 , and Er3+ : 4 S3/2 0 → 4 I15/2 +Ho3+ : 5 F5 → 5 I8 transitions, respectively. No visible upconversion quenching phenomenon is observed when three rare-earth ions are codoped together in tellurite glasses. In contrast, the upconversion intensity of red and green emissions in Er3+ , Yb3+ , and Ho3+ codoped glasses is enhanced largely when compared with Er3+ /Yb3+ -codoped glasses. The dependence of upconversion intensities on excitation power and the possible upconversion mechanisms are evaluated. The three emissions are based on two-photon absorption processes.
