摘要: A phosphor member disclosed in one embodiment includes: a phosphor portion including a first surface and a second surface; and a surrounding portion connected to an outer edge of the first surface and connected to an outer edge of the second surface. In a plan view viewed in a direction perpendicular to the first surface, the first surface has a shape including a first region with a width in a second direction perpendicular to a first direction, the width in the second direction increasing along the first direction. A maximum width of the second surface in the second direction is greater than a minimum width of the first surface in the second direction and less than a maximum width of the first surface in the second direction.

摘要: The laser device includes a substrate, a laser element disposed on the substrate for emitting a laser light ray, a light guide member disposed on the substrate, and a wavelength conversion layer. The light guide member is light-transmissible and thermally conductive, and has at least one reflection surface for reflecting the laser light ray from the laser element so as to change travelling direction of the laser light ray. The wavelength conversion layer converts wavelength of the laser light ray from the light guide member to result in a laser beam, and contacts the light guide member so that heat from the wavelength conversion layer is transferred to the substrate through the light guide member.

摘要: In one embodiment the semiconductor laser (1) comprises a carrier (2) and an edge-emitting laser diode (3) which is mounted on the carrier (2) and which comprises an active zone (33) for generating a laser radiation (L) and a facet (30) with a radiation exit region (31). The semiconductor laser (1) further comprises a protective cover (4), preferably a lens for collimation of the laser radiation (L). The protective cover (4) is fastened to the facet (30) and to a side surface (20) of the carrier (2) by means of an adhesive (5). A mean distance between a light entrance side (41) of the protective cover (4) and the facet (30) is at most 60 μm. The semiconductor laser (1) is configured to be operated in a normal atmosphere without additional gas-tight encapsulation.

摘要: Materials containing picocrystalline quantum dots that form artificial atoms are disclosed. The picocrystalline quantum dots (in the form of born icosahedra with a nearly-symmetrical nuclear configuration) can replace corner silicon atoms in a structure that demonstrates both short range and long-range order as determined by x-ray diffraction of actual samples. A novel class of boron-rich compositions that self-assemble from boron, silicon, hydrogen and, optionally, oxygen is also disclosed. The preferred stoichiometric range for the compositions is (B12Hw)xSiyOz with 3≤w≤5, 2≤x≤4, 2≤y≤5 and 0≤z≤3. By varying oxygen content and the presence or absence of a significant impurity such as gold, unique electrical devices can be constructed that improve upon and are compatible with current semiconductor technology.
