Improving the optical response of tellurite glasses via controlled doping of rare earth is the key issue in lasing materials.
Introduction Rare earth doped glasses are attractive due to their widespread applications in sensor, color display, laser technology, optical storage materials and optical communication, to cite a few [1, 2].
The increase in EUrb from 0.226 to 0.308 eV with the increase of Eu3+ concentration is ascribed to the lack of crystalline long range order in glassy materials [18].

Role of Multiwall Carbon Nano Tubes (MWCNT) on Electrical Conductivity of Polymer Composite as Alternative Materials for Bipolar Plate Fuel Cell A.
Furthermore, the effects of MWCNTs incorporated with PP on electrical conductivity of nano composite was also investigated Research Method Materials.
All materials in each formula on Table 1 was blended using Rheomix Haake PolyDrive at 210oC for 20 minutes to produce pellet composites.
One of requirement for bipolar plate materials is electrical conductivity.

Fig.1 Pile layout and finite modeling of sparse pile to control settlement Five materials are included in the analysis, the embankment fill, the cushion, the soft clay, substratum soil, pile and geosynthetic.
We use Duncan-Chang hyperbolic model to describe the choice of embankment fill, cushion, soft clay and substratum soil.The pile and geosynthetic are linear elastic materials.
Each material parameters is as as Table 1.

With the development of materials science and interdisciplinary convergence of disciplines, multi-doped gradually replaced single-doped as the mainstream doping mode due to its application diversity and abundant property of aggregation of each materials [10-12].
But, there is no report on the Co-Ga co-doped in chalcogenid materials.
