Color Locating of Ce³⁺ and Eu²⁺ Doped Calcium Magnesium Chlorosilicate UV-LED Phosphors

Abstract:

Color coordinates (0.1573, 0.0528) and (0.1542, 0.4663) have been identified in Ce³⁺ and Eu²⁺ singly doped calcium magnesium chlorosilicate (CMSC) phosphors, which present the purplish-blue and green lights under ultraviolet (UV) radiation, respectively. In Ce³⁺/Eu²⁺ co-doped CMSC phosphors, with sensitizing the green emission of Eu²⁺, Ce³⁺ co-doping changed the luminescence color from green to bluish-green, presenting a preferable mixed effect from two primary colors. Potential mixture of red phosphors will provide the possibility in achieving the ideal white fluorescence under UV-LED excitation.
