采用传统的熔融法和淬冷法制备了Pr 3+、Er 3+和Nd 3+掺杂的碲酸盐玻璃样品，在488 nm氙灯下观察到Pr 3 +-Er 3 +-Nd 3+三掺杂碲酸盐玻璃样品在800-1100 nm和1250-1650 nm两个超宽近红外发射带。800-1100 nm的发射带是由Pr 3+：3 P1，0→ 1G 4，Pr 3+：1D 2 → 3F 4，3，Er 3+：4S 3/2→ 4 I11/2，Er 3+：4 I11/2→ 4 I15/2、Nd 3+：4F 3/2→ 4 I9/2和Nd 3+：4F 3/2→ 4 I11/2辐射跃迁，而1250-1650 nm发射带由Nd 3+：4F 3/2→ 4 I13/2，Pr 3+：1G 4 → 3 H5，Pr 3+：1D 2 → 1G 4，Pr 3+：3F 3 → 3 H4，和Er 3+：4 I13/2→ 4 I15/2辐射跃迁，后者的半高宽约为296 nm。结果表明，适当浓度的Pr 3+、Er 3+和Nd 3+三掺杂碲酸盐玻璃可同时应用于医学成像、宽带光纤放大器和宽带照明光源等领域。
Pr3+-, Er3+-, and Nd3+-doped tellurite glasses were synthesized via traditional melting and quenching, and two super-broad near-infrared 800–1100 nm and 1250–1650 nm emission bands were observed simultaneously in the as-prepared Pr3+-Er3+-Nd3+tri-doped glass sample under a 488 nm xenon lamp. The 800–1100 nm emission band was caused by the spectral overlapping of Pr3+:3P1,0→1G4, Pr3+:1D2→3F4,3, Er3+:4S3/2→4I11/2, Er3+:4I11/2→4I15/2, Nd3+:4F3/2→4I9/2, and Nd3+:4F3/2→4I11/2radiation transitions, while the 1250–1650 nm emission band was produced by the Nd3+:4F3/2→4I13/2, Pr3+:1G4→3H5, Pr3+:1D2→1G4, Pr3+:3F3→3H4, and Er3+:4I13/2→4I15/2radiation transitions, and the latter had a full width at half maximum (FWHM) of approximately 296 nm. The results demonstrate that tellurite glass tri-doped with appropriate concentrations of Pr3+, Er3+, and Nd3+ions can be applied to many fields such as medical imaging, broadband fiber amplifiers, and broadband lighting sources at the same time.
