Improvement of the Tm 3 + : 3 H 4 level lifetime in silica optical fibres by lowering the local phonon energy
The role of some glass network modifiers on the quantum efficiency of the near-infrared fluorescence from the 3 H 4 level of Tm 3+ ion in silica-based doped fibres is studied. Modifications of the core composition affect the spectroscopic properties of Tm 3+ ion. Adding 17.4 mol% of AlO 3/2 to the core glass caused an increase of the 3 H 4 level lifetime up to 50 µs, 3.6 times higher than in pu...

the effect of authentic listening materials on the listening proficiency of efl learners in the intermediate level
having conducted the experiment and analysed the data, the researcher computed the groups mean scores and variances for the test relating to the research question. as the final atep, a t-test was conodonted for the hypothesis. as noted earlier, the significance level was determined at .05 and .01 respectively. the observed t-value was higher than the critical t-value at. 5 and .01 levels. conse...
