Abstract

발광특성이 우수한 갈레이트계 수용성 형광체 및 그 제조방법을 제공하고 물을 사용하지 않는 건식 전자사진 원리를 도입하여 이 수용성 형광체와 유체로 되어 있는 형광체 조성물을 브라운관 스크린 제조공정에 적용함으로써 발광효율과 색재 현범위를 향상시키고 동일 형광면 휘도에서 전자빔에 의한 전류값을 감소시켜 전자빔 스폿의 감소에 따라 선명도를 증가시킨다.It provides a gallate-based water-soluble phosphor having excellent luminescence properties and a method of manufacturing the same, and introduces a dry electrophotographic principle that does not use water, and applies the phosphor composition composed of this water-soluble phosphor and a fluid to a CRT screen manufacturing process to provide luminous efficiency and colorant. The sharpness is increased by decreasing the electron beam spot by improving the current range and decreasing the current value caused by the electron beam at the same fluorescent surface brightness.
