Sol-Gel Synthesis of Lanthanide-Doped Aluminosilicate Glasses

<p> Doping Praseodymium into Al-Si glass has potential applications in permanent holographic data storage and other optical devices. For this we are using the sol-gel method to produce glass monoliths at relatively low temperatures. The silicon precursor is tetraethylorthosilicate (TEOS) and a...
