| Abstract | Abstract Mg 3.5 Ge 1.25 O 6 :Mn 4+ was synthesized by a solid-state reaction and its photoluminescence characteristics were investigated. The synthesized phosphor showed a narrow emission band between 600 and 700 nm with two clear peaks at 632 and 660 nm and two obscure peaks at 626 and 653 nm due to the 2 E→ 4 A 2 transition of Mn 4+ ( λ ex =405 nm). Red light-emitting diodes (LEDs) were fabricated through the integration of an InGaN UV chip ( λ em =405 nm) and Mg 3.5 Ge 1.25 O 6 :Mn 4+ phosphor in a single package. Red LEDs showed CIE chromaticity with values of x =0.32 and y =0.10 and the color temperature of 4900 K. |
