Abstract

A manufacturing method of an optical member includes providing a raw member, disposing first ions and second ions in the raw member, and heat-treating the raw member with the first and second ions therein such that the first ions are reacted with the second ions in the raw member to form quantum dots in the raw member which forms the optical member.

First claim

What is claimed is:

1. A method of manufacturing an optical member, comprising:
providing a raw member injecting first ions and second ions into the raw member; and
heat-treating the raw member having the first ions and second ions therein to couple the first ions to the second ions within a portion of the raw member, the coupled ions forming quantum dots within the portion of the raw member to form the optical member.

2. The method of claim 1 , wherein the injecting the first and second ions into the raw member comprises:
accelerating the first ions to form a first ion beam;
accelerating the second ions to form a second ion beam;
irradiating the first ion beam to the raw member to inject the first ions into the raw member; and
irradiating the second ion beam to the raw member to inject the second ions into the raw member.

3. The method of claim 1 , wherein the heat-treating the raw member is performed by heating the raw member at a temperature equal to or greater than about 300 degrees Celsius and equal to or less than about 500 degrees Celsius.

4. The method of claim 1 , wherein
the first and second ions are injected into the raw member through a side surface thereof corresponding to a light incident surface of the optical member, and
the injected first and second ions are disposed within a first area portion of the raw member, the first area portion defined from the side surface of the raw member, and
the injected first and second ions are not disposed within a second area portion of the raw member, the second area portion defined as a remaining area portion of the raw member except for the first area portion.

5. The method of claim 1 , wherein the first and second ions are injected into the raw member through a side surface thereof corresponding to a light incident surface of the optical member,
further comprising applying an electric field to the injected first and second ions to move the injected first and second ions within the portion of the raw member and in a first direction away from the side surface of the raw member.

6. The method of claim 1 , wherein the raw member comprises a glass.

7. The method of claim 1 , wherein the first ions have a polarity different from a polarity of the second ions.
