A light emitting apparatus at least includes a light emitting device, a connecting wire structure, and a space-occupation body. The light emitting device is disposed in the space-occupation body, electrically coupled with the connecting wire structure, and emits a first-frequency-range light under a suitable driving voltage. A light emitting surface of the light emitting device structure is covered by a first anti-reflection layer with respect to the first-frequency-range light. A packaging material is filled into the space-occupation body. The packaging material at least includes a luminescent material. The luminescent material is excited by the first-frequency-range light, so as to generate at least a second-frequency-range light. A reflector is disposed on the light emitting surface of the light emitting apparatus, such that the first-frequency-range light is totally or mostly reflected back to the space-occupation body omni-directionally, and the excited second-frequency-range light passes through the reflector.

A vertical organic transistor is disclosed, which includes at least: a collector contact layer disposed on a substrate; a first organic semiconductor layer disposed on the collector contact layer; a base contact layer disposed on the first organic semiconductor layer, wherein the base contact layer comprises no less than two layers of hetero-metal layers or hetero-conductive organic layers; a second organic semiconductor layer disposed on the base contact layer; and an emitter contact layer disposed on the second organic semiconductor layer. Device properties such as output current and I/Irate can be improved by using the vertical organic transistor of this invention.
