Exploring the potential of Eu ions doped heavy metal oxide containing germanium borate glasses for high efficiency red emitting solid-state lasers.

Glasses activated with europium show promising potential for use in applications relating to photonics, in particular solid-state laser generation. In the current work, EuO incorporated gemanium borate glasses were developed and explored their potentiality towards lasing active medium by probing physical, structural, optical and lasing properties in detail. The physical and structural features of each glass indicated the presence of non-bridging oxygens (NBOs) and an enhancement in network stability on account of the inclusion of europium ions into the GeO glass network.

Correlation between size, shape and magnetic anisotropy of CoFeO ferrite nanoparticles.

The present work reports the effect of particle size and shape of CoFeO (CFO) nanoparticles on magnetic properties and their use in device applications as permanent magnets at room temperature. A set of CFO samples with different particle sizes and shapes were synthesized via the polymeric method by sintering at temperatures ranging from 300 °C to 1200 °C. These materials were characterized structurally by x-ray diffraction, morphologically by scanning electron microscopy, and microstructurally by transmission electron microscopy.
