Currently, most of the red colored glasses are still produced using cadmium sulfoselenide, despite its high toxicity. Alternative solutions, more environmentally friendly, have been sought, most of them going through the use of gold or copper nanopar

Pure and doped (zinc and iron) nanocrystalline titania powders were prepared by the sol–gel route. Doping tends to change the existing crystalline phases and their degree of crystallinity, but particle size distribution and morphology of the partic
