Luminescing member, process for preparation thereof, and electroluminescent device employing same.

摘要

A luminescing member emits light as a result of application of excitation energy thereto, wherein a luminescing part comprises on ultrafine particle film formed by deposition of ultrafine particles. It is preferred that the ultrafine particles comprises an amorphous A:Ox or an amorphous A:O:H having an A-O-A bond and an A-OH bond, and the element A is at least one element selected from the group consisting of Si, C and Ge.
