Effect of mixed alkali ions on the structural and spectroscopic properties of Nd3+ doped silicate glasses
Montoya Matos, Israel Roger; Balzaretti N.M. (Elsevier, 2024)Acceso abiertoIn the present work the effect of alkali ions (Li, Na, K) and the combination of them on structural and spectroscopic properties of Nd3+ doped silicate glasses were systematically investigated. Results from infrared and ... -
High pressure effect in the near-infrared emission of Nd3+-doped alkali silicate glasses
Montoya Matos, Israel Roger; Balzaretti, Naira Maria (Taylor & Francis, 2022)Acceso restringidoThe effect of high pressure (7.7 GPa) densification on the absorption and near-infrared emission of Nd-doped lithium, sodium and potassium disilicate glasses was investigated. Judd-Ofelt parameters O¿ (¿ = 2, 4 and 6) were ... -
Influence of Alkali Metal Ions on the Structural and Spectroscopic Properties of Sm3+-Doped Silicate Glasses
Montoya Matos, Israel Roger (Multidisciplinary Digital Publishing Institute (MDPI), 2023)Acceso abiertoIn the present work, the influence of alkali ions (Li, Na, K) on the structural and spectroscopic properties of silica glasses doped with Sm3+ was investigated. Infrared and Raman spectroscopy techniques were used to ...
