Abstract
Official abstract text for this publication.
A light emitting element includes a light emitting member that is formed of at least two kinds of an oxide material and has a plate shape; and a light transmitting member that collimates a light emitted from the light emitting member and has a plano-convex shape, in which a contact portion between the light transmitting member and the light emitting member is continuous.
First claim
Opening claim text (preview).
What is claimed is: 1. A light emitting element comprising: a light emitting member that is formed of at least two kinds of an oxide material and has a plate shape; and a light transmitting member that collimates a light emitted from the light emitting member and has a plano-convex shape, wherein a contact portion between the light transmitting member and the light emitting member is continuous, wherein the light emitting member is formed of at least one material not having a luminescent center and a material having the luminescent center, and wherein the light transmitting member is formed of a material substantially the same as the material of the light emitting member, not having the luminescent center. 2. The light emitting element of claim 1 , wherein in the contact portion, the material not having the luminescent center and the material having the luminescent center are distributed in a state of being three-dimensionally entwined with each other. 3. The light emitting element of claim 1 , wherein the material not having the luminescent center is Al 2 O 3 , and wherein the material having the luminescent center is Y 3 Al 5 O 12 containing Ce. 4. The light emitting element of claim 2 , wherein the material not having the luminescent center is Al 2 O 3 , and wherein the material having the luminescent center is Y 3 Al 5 O 12 containing Ce.
