A　trichromatic　phosphor-free　white　light-emitting　diode　(LED)　has　been　implemented　by　using　adhesive　bonding　scheme.　The　device　has　been　operated　as　a　three-terminal　device　with　independent　electrical　control　of　an　AlGaInP-based　red　LED　chip　and　a　GaN-based　dual-wavelength　(blue　and　green)　LED　chip.　As　25mA　and　60　mA　was　injected　into　the　red　and　blue-green　LED　chips　at　room　temperature　respectively,　white　light　emission　could　be　observed　with　CIE　chromaticity　coordinates　(0.3330,　0.3241),　correlated　color　temperature　Tc=5467K　and　optical　power　Φe=2.223mW.　The　electroluminescence　measurements　also　show　that　the　emitted　white　light　is　composed　of　blue,　green　and　red　lights,　centered　at　around　452nm,　517nm　and　632nm.　The　fabrication　and　the　electrical　and　optical　performances　of　such　white　LED　were　described.　©　2009　SPIE-OSA-IEEE.
