Dynamic Properties of Inorganic Glasses

小行星9225072 该计划继续作为一个更新计划，研究玻璃中的离子动力学，反映在电导率的频率依赖性，核自旋弛豫（NSR），以及两者之间的相关性。 噪音感应强的比率及s须以频率及温度的函数量度。 电荷离域（键合）及其对离子运动的影响将被系统地表征。 %%%% 这个计划的目的是调查和了解玻璃中的离子运动。 它试图回答的问题，如，什么是起源的电导率在适度的低温？移动的离子和离子电荷补偿中心或网络之间的化学键的确切性质是什么？ 玻璃作为光通信领域的主要组成部分，其重要性日益增加。 对这一点的基本理解可以产生有助于设计新应用的新眼镜的信息。 ****

9225072 Jain This proposed program continues as a renewal program, which investigates ion dynamics in glasses as reflected in the frequency dependence of electrical conductivity s, the nuclear spin relaxation (NSR), and in the correlation between the two. NSR rate and s are to be measured as a function of frequency and temperature. Charge delocalization (bonding) and its effect on ion movement are to be characterized systematically. %%%% This proposed program aims to investigate and to understand the ion movement in glasses. It seeks to answer questions such as, what is the origin of electrical conductivity at moderately low temperature?, and what is exact nature of chemical bond between a mobile ion and ion charge compensation center or network at large? Glass is assuming ever-increasing importance as a major component of the optical communication world. Fundamental understanding of this kind can produce information which will aid out design of new glasses for new applications. ****
