摘要： A light-emitting diode (1) is furnished with a semiconductor laminate (6), optically reflective layers (17) and (19), an optically reflective film (25), and a phosphorescent plate (27). The laminate (6) is formed by an n-type cladding layer (9), an active layer (11), a p-type cladding layer (13), and a p-type contact layer (15), laminated in order onto a substrate (7). The optically reflective layers (17) and (19) are provided respectively on the p-type contact layer (15) and on the back side (7b) of the substrate (7). The optically reflective film (25) is provided on three side surfaces of the laminate (6). The phosphorescent plate (27) is mounted on a side face, among the side faces of the laminate (6), on which there is no optically reflective film (25). Blue light (L1) output from the active layer (11) is reflected at each of the optically reflective layers, and is gathered on the side face on which the phosphorescent plate (27) is provided. A portion of the blue light (L1) turns into yellow light (2) in the phosphorescent plate (27), and white light derived from the blue light (L1) and yellow light (L2) is emitted.

摘要： Surfaces of diamond crystals are examined by coating the surfaces with thin metal films, launching laser beams to the diamond surfaces in a slanting angle, detecting defects and particles on the diamond surfaces by the scattering of beams and counting the defects and particles by a laser scanning surface defect detection apparatus. Diamond SAW devices should be made on the diamond films or bulks with the defect density less than 300 particles cm−2. Preferably, the diamond surfaces should have roughness less than Ra20 nm. Diamond SAW filters can be produced by depositing a piezoelectric film and making interdigital transducers on the low-defect density diamond crystals.
