A two-step solid-state reaction to synthesize the yellow persistent Gd3Al2Ga3O12:Ce3+phosphor with an enhanced optical performance for AC-LEDs

By using a two-step solid-state reaction to synthesize the yellow-persistent Gd3Al2Ga3O12:Ce3+ phosphor, both the luminescence and afterglow properties were greatly enhanced. Its internal quantum efficiency reaches as high as 81.9%, indicating its promising application in reducing the flicker effect in AC-LED-based white light systems.
