“…Raman, 50 NMR, 51 electron paramagnetic resonance 52,53 and Mö ssbauer spectroscopies 54 are useful for establishing a relationship between structure and properties of these materials; together with absorption and linear emission spectroscopies, the environment of RE elements can be analysed. The change of the lattice parameters when the RE ion is incorporated into the crystal structure can be measured by refined XRD patterns.…”

Rare earth (RE) doped oxyfluoride glass ceramics possess interesting optical properties with applications in telecommunications and optoelectronics, such as solid state lasers, optical amplifiers, etc. These materials combine the transparency and mechanical and chemical resistance of aluminosilicate glasses with the low phonon energy and facile incorporation of RE ions in the fluoride crystals. The incorporation of RE ions in the crystalline phases enhances the laser emission intensity, a major property of these materials. Transparency is achieved when crystal size is in the nanometric scale, usually below 40 nm, which avoids light scattering. A strict control of the nucleation and crystal growth processes is therefore necessary which requires a deep knowledge of the crystallisation mechanisms. The great activity and publications in this field in the last decades merit a review providing a comparative study of the different nanoglass ceramic systems, their structural and optical characterisation and their main properties and applications. This is the objective of this review paper which includes 232 references. A general discussion on glass nucleation and crystallisation theories and more relevant crystallisation parameters and characterisation techniques are put forward in the first section of the review, focused on nanocrystallisation processes in oxyfluoride systems. In the second section, the principal RE doped glass ceramics are presented. After a general introduction about the luminescence processes, including up-and down-conversion, the behaviour of RE elements in glasses and crystals are discussed. Glass ceramic compositions have been divided as follows: glass ceramics with a glass composition following Wang and Ohwaki's oxyfluoride glass ceramic, 1 ; and glass ceramics with different matrix compositions, arranged by crystalline phases. Relevant properties, mainly optical and laser, are described in each system along with the most relevant applications of these materials.

“…Pr 3+ doped glasses have transition in the visible region. Some spectral studies have been reported for Pr 3+ doped borate and phosphate glasses earlier [5][6][7][8][9][10][11][12][13][14][15][16] . Recent studies reported 17 on the applications of Pr 3+ doped borophosphate glasses.…”

We have successfully synthesized Pr 2 O 5 doped borate glasses by conventional rapid melt quench method. The XRD pattern indicates the amorphous nature of Pr 2 O 5 doped borate glass. An optical property of prepared borate glass was studied using the Photoluminescence spectrum. Determination and differentiation of the various vibrational modes were done using FTIR spectroscopy studies. Raman spectroscopy of Pr 2 O 5 doped borate glass was also carried out. Thermal analyses of the glasses were done using the TGA/ DTA and DSC analysis. The dielectric properties such as dielectric constant, the dielectric loss and AC conductivity of the Pr 2 O 5 doped borate glass were studied in the different frequencies and temperature.

“…Rare earth-doped glass ceramics are considered to be one of the promising materials for fiber amplifiers, lasers, fluorescent devices and white light emitting diode (LED) [1][2][3] due to their outstanding optical properties, good thermal stability and physicochemical properties [4,5]. Among rare earth ions, trivalent europium (Eu3 + ) ion is the best candidate to be used as a probe to investigate the local structure, and Eu 3+ -doped materials are frequently used in photonic applications as red phosphors for field emission technology [6].…”

Phase Separation and Luminescence of Eu<sub>2</sub>O<sub>3</sub> Doped Boron Silicate Glass

Eu2O3 doped boron silicate glass appearing phase separation have been prepared and characterized. The heat treatment temperature was determined by DTA, the microstructure and optical properties of the glass were studied by SEM and fluorescence spectra. The adding of Eu2O3 restrained the phase separation and crystallization of the glass. Eu ions exist in the glass samples as the Eu3+ ions, rather than the Eu2+ ions. As the heat treatment temperature increases, the phase separation region increased gradually, and the luminescent intensity increases.
