摘要： PROBLEM TO BE SOLVED: To further improve efficiency of an LED light-emitting device emitting white light. SOLUTION: The LED light-emitting device shown in Fig. 1 includes an LED 10, a red light-emitting R phosphor layer 11, a yellow light-emitting Y phosphor layer 12, and a blue light-emitting B phosphor layer 13. The phosphor layers are stacked in the sequence of the Y phosphor layer 12, the B phosphor layer 13, and the R phosphor layer 11 from the side close to the LED 10. The stacking sequence of the Y phosphor layer 12 and the B phosphor layer 13 is first determined to prevent these layers from interacting with each other, and the stacking sequence of the R phosphor layer 11 and the Y phosphor layer 12 and the stacking sequence of the R phosphor layer 11 and the B phosphor layer 13 are determined by a determination expression D. By determining the stacking sequence like that, degradation of the conversion efficiency of the phosphors due to concentration quenching can be considered, the emission efficiency of the LED light-emitting device is improved.

摘要： PROBLEM TO BE SOLVED: To improve a responding speed of a III nitride compound semiconductor light-emitting element for optical communication. SOLUTION: In the light-emitting element for the communication using a III nitride compound semiconductor, a light-emitting layer has a quantum well structure, in which the number of well layers is set to an arbitrary number in the range of 1 to 5, and an area of a light-emitting unit of the emitting layer is set at 0.001-0.032 mm 2 . Thus, a high-frequency cut-off frequency becomes 50 MHz or higher, and the high-frequency cut-off frequency is improved 1.7 times as high as that at 30 MHz of conventional elements. A light, having a wavelength range of low transmission loss of a plastic fiber of 450-550 nm, can be emitted from the III nitride compound semiconductor light-emitting element. As a result, a simple LAN (local area network) using the plastic fiber can be constructed at low cost. COPYRIGHT: (C)2004,JPO
