1. Breakdown-induced light emission and poling dynamics of porous fluoropolymers

Author

Zhukov, S. and von Seggem, H.

Subjects
Dielectric films -- Electric properties, Thin films -- Electric properties, Fluoropolymers -- Electric properties, Physics
Abstract

The light emission during corona poling of individual films of expanded polytetrafluoroethylene (ePTFE) with nominal porosity and of the same film sandwiched between two solid poly-fluoroethylene propylene copolymer (FEP) films is investigated. The results have described the drastic difference in piezoactivity between individual porous films and sandwiched structures.

3. Influence of Li-codoping on the radiation hardness of CsBr: [Eu.super.2+]

Author

Zimmermann, J., Hesse, S., von Seggem, H., Knupfer, W.., and Fuchs, M.

Subjects
Semiconductor doping -- Research, Hardness -- Analysis, Phosphors -- Thermal properties, Physics
Abstract

The effect of Li-codoping on the radiation hardness of x-ray storage phosphor CsBr: [Eu.super.2+] is investigated. The results show that addition of [Li.super.+] into CsBr: [Eu.super.2+] decreases the generation of M-centers which partially improves the radiation hardness.
