A study of structural, optical and dielectric properties of Eu2O3 doped borate glass

Abstract

Recent technological applications have generated more interest in the studies of different types of glasses. The wide applications of glasses take place due to their interesting properties such as low thermal expansion, high softening temperature, high resistance to chemical attack, high refractive index with low dispersion and mechanical strength. Eu 2 O 3 doped borate glasses were successfully synthesized by melt quenching method. The X-ray diffraction (XRD) spectra revealed that these glasses had amorphous nature. Optical properties of prepared samples were characterized by photoluminescence studies. The dielectric properties of glass samples were studied for different frequencies and different temperatures.

Luminescence Emission in Borotellurite Glass Containing Manganese Nanoparticles Doped Eu³⁺ Ions

“…However beyond 1 mol %, the emission intensity 108 Solid State Science and Technology XXIX decreases as a result of concentration quenching on the luminescence. Generally, it is found that an excessive doping of emission spectrum ion in inorganic materials could significantly lower the emission intensity [11]. This result is consistent with Bandi et al, (2012) who claimed that this phenomenon is known as the concentration quenching [12].…”
