1. Tellurite glass is a particularly attractive candidate due to its higher nonlinear coefficient. Dispersion design has an important effect on generating broadband and flat supercontinuum output.

2. XRD and FE-SEM analysis results show that tellurite films can be prepared by sol-gel method using tellurium 1,2-propylene diglycollate as raw material.

3. Sodium tellurite glasses are considered as potential candidates for non-linear optical applications because of high refractive index values and wide infrared transmittance.

4. Pr ~ ( 3 + ) doped bismuth tellurite glass with molar composition 7.5 Li _ 2 O - 7.5 K _ 2 O - 5 BaO - 5 Bi _ 2 O _ 3 - 75 TeO _ 2.

5. These features make multi-component tellurite glasses are very suitable for ultra-broadband fiber Raman amplifiers in large-capacity photonic networks.

6. Further treatment with Tellurite would kill bacteria missed by the phages.

7. Rare earth ions doped tellurite glasses are kinds of upconversion fluorescence materials which have good application prospect.

8. This paper reported a kind of tellurite glass with new composition,(sentence dictionary) which can improve the upconversion fluorescence efficiencies.

9. Resistance experiments also were conducted with Tellurite, a compound toxic to bacteria.

10. In this letter, we introduce the mechanism of upconversion fiber lasers, and review the research progress of tellurite glasses on upconversion.

11. Its main characteristic parameters have been obtained, comparisons with reported properties of tellurite glass and heavy flint glasses have been made.

12. Methods:To observe the cultural characteristics with the medium of inclined plane of egg, agar plate with blood and potassium tellurite, and broth.

13. It is found that there are intense radiation trapping and concentration quenching effect in erbium-doped tellurite glasses.

14. We outlined the history of optic amplifiers, analysed the advantages and disadvantages of EDFA and FRA, and the application area of rare earth doped tellurite glass amplification fiber.

15. The investigation results of this work provide theoretical foundation and technical support for the further research on rare-earth-doped tellurite glass fiber amplifier and laser.

16. As host materials for use in Er-doped fiber amplifier(EDFA) and Tm-doped fiber amplifier(TDFA), tellurite glasses have played an important role in active optical fiber for broadband amplification.
