Yellow phosphors Ba2Mg(PO4)2: Eu2+ fit for white light-emitting diodes prepared with sol-gel precursor route

Luminescence and energy transfer of single-phase white-emitting phosphor Ba2Mg(PO4)2:Ce3+, Eu2+ for white LEDs

“…Its physical and chemical properties are stable. Although the luminescence performance of Ba 2 -Mg(PO 4 ) 2 :Eu 2+ has been widely investigated, [30][31][32][33][34][35][36] however, a systematic study on the energy transfer between Eu 2+ and Ce 3+ in Ba 2 Mg(PO 4 ) 2 was not reported. In this work, the crystal structure of Ba 2 Mg(PO 4 ) 2 and preferred crystallographic sites for activators were reported.…”

Luminescence and energy transfer of Tm3+ and Dy3+ co-doped Na3ScSi2O7 phosphors

“…5,6 The current WLED is formed by combining the InGaN-based blue LED chip with the yellow luminous YAG:Ce 3+ phosphor. 7,8 An alternative method is to use a NUV LED chip to stimulate RGB (red, blue, green) phosphors to obtain white light, which is the most popular type in the market. However, there are still some problems in the realization of white light through polyphase phosphors, such as proportion control, color absorption, color subtraction and so on.…”
