摘要：

This paper reports on the development and the near infra-red emission(NIR) analysis of Er3+/Yb3+ and Er3+/Tm3+ ions doped TeO2 - B2O3 - ZnO - Li2O glasses for tunable laser and optical fiber amplification. From the measured near infra-red emission spectra of Er3+/Yb3+, Er3+/Tm3+: ZLiBT glasses have revealed the prominent near infra-red emission bands at 1532 nm (I-4(13/2) -> I-4(15/2)), with an excitation wavelength of lambda(exci) = 515 nm (Ar+ ion laser). The full width at half-maxima (FWHM) values are also estimated from the measured near infra-red emission spectra of the glasses. Based on spectral results, broad near infra-red emissions should have potential applications in broadly tunable laser sources and broad band optical amplification at low-loss telecommunication windows.
