A novel highly electrically conductive silver paste is prepared. With the addition of suitable reactive components and the appropriate binder composition, good interconnection between the silver particles is established during the curing process of the silver paste, which enhances its electrical conductivity. The composition, reaction mechanism, morphology of the silver particles and performance of the silver pastes are discussed.

Metal-dielectric multiple-band high-reflection coatings are designed as induced filters and fabricated by reactive deposition. Ta(2)O(5) and SiO(2) are used as high- and low-refractive-index layers, and Cr and Al are used as bonding and reflective layers, respectively, for constructing the filters. The metal-dielectric coatings are deposited on a light-shaping flexible plastic substrate for use as a screen with high-contrast enhancement performance. This screen was suitable for miniprojectors with red, green, and blue LEDs as light sources. Mechanical properties such as stress, hardness, and adhesive strength of these multilayer films are investigated also.
