Praseodymia-silica glass samples with high praseodymia content (5 wt%) were prepared by the sol-gel process. Amino alkoxy silane was used to immobilize the Pr+3 cation in the silica (derived from tetraethyl orthosilicate) matrix. The gel to glass transformation was examined by ultraviolet, visible, near infrared and Fourier transform infrared spectroscopy at different stages of drying/densification up to 1000°C. The X-ray microanalysis for praseodymium throughout the bulk glass samples confirmed the homogeneous distribution of the Pr+3 in the matrix.

Abstract
Praseodymia-silica glass samples with high praseodymia content (5 wt%) were prepared by the sol-gel process. Amino alkoxy silane was used to immobilize the Pr+3 cation in the silica (derived from tetraethyl orthosilicate) matrix. The gel to glass transformation was examined by ultraviolet, visible, near infrared and Fourier transform infrared spectroscopy at different stages of drying/densification up to 1000°C. The X-ray microanalysis for praseodymium throughout the bulk glass samples confirmed the homogeneous distribution of the Pr+3 in the matrix.File in questo prodotto:
