Class Information
Number: 313/498
Name: Electric lamp and discharge devices > With luminescent solid or liquid material > Solid-state type
Description: Subject matter in which the luminescent material is an insulating material that emits light based on the principle of intrinsic luminescence, i.e., where an applied electric field generates free carriers in the device (since the material, being an insulator, has no free carriers to be accelerated by the applied field) to initiate light emission mechanism(s) in the material, or other solid-state material (e.g., semiconductor) which either operates by a mechanism not `elsewhere classified, or only nominally recites a mechanism (e.g., injection luminescence) elsewhere classified.
