Abstract

There are provided an yttrium oxide composition having particle size of 25 nm or less, a method of preparing the same and a method of forming an yttrium oxide layer using the same. The yttrium oxide composition is prepared by dissolving an yttrium salt into a solvent to prepare an yttrium salt solution, and adding a basic compound to the yttrium salt solution to adjust a pH value to a range of 3.7 to 7. The yttrium oxide composition can form an yttrium oxide layer having improved properties since the composition has particle size of 25 nm or less and uniform particle distribution.

Description

technical field

[0001] The present invention relates to a composition of yttrium oxide, a method for preparing the composition and a method for forming a layer of yttrium oxide using the composition, and in particular to a composition of yttrium oxide having a particle size equal to or smaller than 25 nm , a method of making such a composition and a method of forming an yttrium oxide layer using such a composition. Background technique

[0002] The image quality of a display depends to a large extent on the quality of its light-giving part. In general, the quality of the light-giving portion is determined by properties such as the intensity and brightness uniformity of the light generated by the light-giving portion. Recently, a surface light source device such as a flat fluorescent lamp (FFL) having improved luminance uniformity has been developed.

[0003] When the brightness gradually decreases over time, the life of the surface light source device also ends. The main ...
