“…It was thought that Ce 3+ /Ce 4+ cannot sensitize the luminescence of Tb 3+ in silicate glasses. It has been reported that Ce 3+ ions can sensitize Tb 3+ ions and strongly enhance the luminescence coming from Tb 3+ ions in Ce 3+ and Tb 3+ codoped borate glasses [1]. This is not in agreement with the experimental result in this paper.…”

“…Rare earth ion doped glasses have obtained considerable interest due to their more homogenous luminescence, lower cost, greater ease of production and possibility of adjusting composition in comparison with other luminescent materials [1][2][3]. Among rare earth ion doped glasses, Tb 3+ doped silicate glasses have been extensively investigated since they possess higher luminescent intensities [4][5][6].…”

Sol–Gel Synthesis of Tunable Cerium Titanate Materials

Cerium titanate structures present a high technological interest because of their optical and catalytic properties. This work reports the synthesis of these materials by a sol–gel methodology that allows mixed oxides with TiIV/CeIII, TiIV/CeIV or TiIV/CeIII–CeIV species to be obtained. Crystallization of CeO2–TiO2 mixed oxides and Ce2Ti2O7 pyrochlore phase was corroborated by XRD and Raman spectroscopy. Magnetic and EPR measurements were performed in order to clarify the oxidation state of the cerium ions in the system as a result of the easy oxidation of CeIII. The firing atmosphere is crucial for the CeIII/CeIV ratio, which is responsible for the different structure, but it also affects the colouration (yellow, green, brown). This methodology offers the possibility to modulate the Ce3+/Ce4+ content and particle sizes providing more ecological coloured pigments based on rare earth elements that could be interesting materials for advanced applications in catalysis.(© Wiley‐VCH Verlag GmbH & Co.

“…The spectroscopic investigations and intensity analysis play a prominent role in characterizing the rare earth-doped glasses as well as to understand some fundamental phenomenon and interactions involving radiation and matter. Rare earth-doped borate glasses have attracted much attention due to their high transparency, low melting point, easily shaped and cost effective properties [2]. The oxyfluoride glasses are expected to have chemical durability and thermal stability representing a compromise between pure fluoride and oxide glasses with flexible optical properties [3].…”
