Photorefraction in lead tin-fluorophosphate glasses.

Up and Down Frequency-Conversion Properties of Eu3+ Doped Lead Fluorophosphate Nanoglass Ceramics

Europium doped transparent lead fluorophosphate glass ceramics successfully were prepared with heat treatment of precourse glasses at temperature above glass transition (Tg). X-ray diffraction (XRD) experiment evidenced the formation of PbF2 nanocrystals in glassy matrix. The emission spectra investigation indicate that considerable amount of Eu3+ ions were trapped in crystalline phase, and the...

Low Temperature Glasses

TWRS wastes contain certain chemical components which, either because of their limited solubility or volatilization at high temperatures, present problems for conventional vitrification technologies. The current task completed by BNL concerns the use of low temperature glasses for tank waste remediation. A literature review of existing technologies highlighted lead-iron-phosphate glasses, with ...

Optical properties of Nd3+ ions in fluorophosphate glasses

Research and development of new neodymium laser glasses

This work presents a brief introduction on three kinds of newly developed Nd3+-doped laser glasses in Shanghai Institute of Optics and Fine Mechanics (SIOM), China. Two Nd3+-doped phosphate glasses with lower thermal expansion coefficient and thermal shock resistance 4 times higher than that of N31 glass are developed for laser processing. Nd:Silicate and Nd:Aluminate glasses with peak emission...

Development and Testing of a Glass Waste Form for the Immobilization of Plutonium

Two alkali-tin-silicate (ATS) glasses have been prepared at Argonne National Laboratory (ANL) as part of our ongoing research in radioactive waste glass development. These glasses dissolved 5% and approximately 7% Pu. Early corrosion test results indicate that Pu-bearing ATS glass is extremely durable. The initial goal in this project concerned equally both the solubility of Pu and the durabili...
