초록
Eu2+ 활성제 이온의 농도가 100% 이므로 농도 소광 효과가 없는 EuGa2S4와 Eu2Ga2S5 형광체를 800~1050℃의 온도 범위에서 고상법으로 합성하였다. EuGa2S4와 Eu2Ga2S5 형광체의 최대 발광 세기의 파장(λmax)은 각각 546과 581 nm이다. X-선 회절 패턴 및 발광 특성을 조사한 결과 EuGa2S4와 Eu2Ga2S5 형광체는 각각 낮은 온도 범위(800~900℃)와 높은 온도 범위(1000 ~1050℃)에서 형성됨을 확인하였다.
Abstract
Non-concentration quenching EuGa2S4 and Eu2Ga2S5 phosphors, in which the concentration of Eu2+ activator ion is 100%, were synthesized by a solid state reaction at temperature range from 800 to 1050 ℃. The wavelength of maximum intensity (λmax) of EuGa2S4 and Eu2Ga2S5 phosphors are 546 and 581 nm, respectively. An examination of the Xray diffraction patterns and photoluminescent properties of EuGa2S4 and Eu2Ga2S5 phosphors revealed that EuGa2S4 and Eu2Ga2S5 phosphors were formed at lower temperature range (800~900 ℃) and higher temperature range (1000~1050 ℃), respectively.
