Abstract

기존의 음극선관용 적색 형광체의 호스트로서 스트론튬을 사용하여 전계발광용과 전자선 여기용으로의 활용 또는 가능한 적색 형광체로서, 그 몸체의 색 자체가 적색이기에 기존의 적색 형광체 보다 우수한 콘트라스트를 갖는 적색 형광체이다.A red phosphor that can be utilized for electroluminescence and electron beam excitation or strontium by using strontium as a host of a conventional red phosphor for a cathode ray tube. Since the color of the body itself is red, it has a better contrast than a conventional red phosphor.
