摘要：

The types of solvent affected the properties of nano-sized Pb-based glass powders prepared by flame spray pyrolysis. The glass powders prepared from the alcohol-free spray solution was Pb rich in comparison with the composition of the spray solution. However, the addition of alcohol to the spray solution decreased the atomic ratio of Pb to Si components in the nano-sized glass powders. The addition of ethyl alcohol or methyl alcohol to the spray solution improved the characteristics of the inner structures and transmittances of the dielectric layers fired at a low temperature of 460 degrees C. The transmittances of the dielectric layers formed from the nano-sized glass powders obtained from the spray solution containing alcohol were higher than 80% within the visible range at a low firing temperature of 460 degrees C. However, the transmittances of the dielectric layers formed from the micron-sized and nano-sized glass powders had similar transmittances higher than 90% in the visible range at the firing temperature of 520 degrees C.
