“…This process could be also associated with formation of entities like ZnTeO 3 , Zn 2 Te 3 O 8 and Bi 2 Te 4 O 11 [16,17]. The broadening of RF2 into low frequency region reflects most probably formation of following linkages: O-Te-O [11], Te-O-Bi [17], and Bi-O-Bi [18]. Origin of RF1 remains to be not fully clear.…”

“…The lowest frequency peak (boson peak), corresponds to the collective modes of local structures [29,30]. The band at 270 cm À 1 is due to the vibrational mode of Ti-O bonds [31,32]. With the decrease of TiO 2 , the intensity of peak is weakening, and shifts to lower frequency.…”

“…[224][225][226][227][228] One interesting open point relevant for this work is the possible substitution of Pb by Bi as an additive to achieve water durable ultra low melting tin fluorophosphate glasses, 153,220 i.e. 45,73,113,120,123,126,[229][230][231][232][233][234][235][236][237][238][239][240][241] Although toxicity of V 2 O 5 is a cause of concern (the section on 'Toxicity of elements in glasses' in Supplementary Material 1 http:// dx.doi.org/10.1179/1743280412Y.0000000010.S1), these oxides are useful as additives in small amounts, to improve adhesion, wetting and durability, suppress crystallisation in glasses and reduce working temperatures. 35,[56][57][58]146,198,207,216,222,242 …”

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...
