“…From this figure it can be seen that the density and molar volume decreases with the addition and increase of Li 2 O content. This behaviors of the studied glasses are agreed with reported data elsewhere [5]. The decrease in the density ( Fig.…”

“…These unique properties make tellurite glasses potential candidate materials for laser hosts, IR window and many optical devices like optical switches, wave guides, etc. [2,5]. Pure tellurium oxide (TeO 2 ) does not easily form a glass by conventional melting methods where a pure TeO 2 glass has a poor chemically durability and crystallizes easily [2].…”

“…A great deal of research has been focused on the fabrication and characterization of glass and glassceramics based phosphors in order to obtain efficient luminescent materials for fluorescent lamps, neon discharge lamps, oscilloscopes, color televisions, light emitting diode and many other displays and lighting devices [1][2][3]. Glass containing zinc oxide (ZnO) is one of the most preferred glass materials due to their good mechanical properties and low softening point compared with other glass systems [4][5][6][7]. This type of glass is a promising optical host material in solid-state laser when doped with transition metal and rare earth ions because this glass exhibits high transparency from UV to IR region, low refractive index and thermal expansion coefficient with high thermal stability and possibility of incorporating large number of dopant ions [8,9].…”

This paper presents a comprehensive study on thermal, structural and optical properties of novel willemite glass-ceramics. The precursor glass in the ZnO-SLS glass system was successfully prepared using conventional meltquenching technique and willemite (Zn 2 SiO 4 ) glass-ceramics were derived from this precursor glass by a control crystallization process. The effect of heat-treatment temperature on the phase transformation, morphology and size of Zn 2 SiO 4 crystal phase was examined using X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM) techniques. Furthermore, fourier transform infrared reflection (FTIR) spectroscopy was used to evaluate the Zn 2 SiO 4 crystal structural evolution. The average size of Zn 2 SiO 4 crystallite obtained from calculation of XRD is found to be in the range 30-60 nm, whereas the grain size observed in FESEM is in range of 200-400 nm. The appearance of SiO 2 , ZnO 4 and Zn-O-Si bands detected from FTIR indicate the formation of Zn 2 SiO 4 crystal phase. Besides, the study of the optical band gap has found that optical band gap of the glass-ceramics decreased as the heat treatment temperature increased. The photoluminescence spectra of willemite glass-ceramics exhibit two different emissions around 525 nm (green) and 585 nm (yellow); exhibit a characteristic of broad absorption band around 260 nm. These two different spectra reveal that the luminescence performance of the willemite glass-ceramics was enhanced with the progression of heat treatment temperature due to different located energy levels of the b-Zn 2 SiO 4 and a-Zn 2 SiO 4 crystalline phase. Such luminescent glass-ceramics was expected to find potential applications in phosphors and opto-electronic devices.

The present work critically reviews the scientific and patent literature on low melting bismuth based oxide glass frits in materials for electronics, sensors and related applications such as sealing glasses, solar cells, architectural and automotive glass, the main motivation being to replace lead based materials by environmentally more benign ones. Due to similar glass forming properties of Bi and Pb, Bi based glasses are the closest 'drop-in' alternative for lead bearing formulations, and are therefore actually replacing them in many applications, helped also by previous experience with Bi containing materials in thick film technology and component metallisations. The outstanding issues are discussed, e.g. matching the lowest processing temperatures achieved by the classical lead based glasses without sacrificing durability and stability, as well as stability versus chemical reduction. Finally, consideration is also given to special 'heavy' glasses (often containing Bi and Pb together) that are useful in fields such as optics, superconductors and nuclear technology, as well as to specific Bi 2 O 3 containing crystalline compounds.Keywords: Glasses, Bismuth, Bi 2 O 3 , Electronics, Optics, Thick film technology, Sensors Introduction Low melting glasses in electronics and other applicationsAs for ceramics, inorganic glasses, glass-ceramic and glaze materials have long gone beyond their traditional uses to address a wide array of modern technological challenges, Owing to performance and cost criteria, most standard glasses have relatively high softening points. However, there are many technological applications where a low softening temperature is required, in order to lower energy expenditure, avoid damaging devices in contact with the glass during processing or ensure compatibility with other materials:(i) hermetic sealing of packages, lamps, electrical feedthroughs and semiconductor devices 13,14,16,17,19,44,45 (ii) hermetic sealing and mechanical attachment of sensors 23,27 ( Fig. 1) (iii) encapsulation of semiconductor devices 29,30 (iv) overglazing of automotive, packaging and architectural glass 33,34,[46][47][48] (v) photovoltaic (PV) solar cell technology -conductors and contacts 42,43,[49][50][51][52][53] (vi) enamelling of aluminium in architecture and home appliances 35,[54][55][56][57][58] (vii) thick film (TF) electronics and other devices 21,22,24,25,27,59 (Fig. 1, the section on 'PbO in low melting frits and TF technology'); especially, special low firing compositions for fabrication of circuits and sensors on glass or metals. 1,28,[66][67][68][69][70][71][72] For these applications, glasses are often formulated as frits (e.g. finely divided powder), which may be applied, dispersed in a suitable medium, onto a substrate by various methods such as slip casting, screen printing, roller/curtain coating, spraying, dispensing and electrophoresis, or as preforms for sealing. Classically, the aforementioned applications have to a great extent used lead based glasses, which have a rather unique combinat...
