Abstract: A thin-film white LED chip includes a transparent substrate, a first transparent electrode, an emissive structure, a second transparent electrode, and a first phosphorescent/fluorescent layer respectively arranged in sequence. The emissive structure includes an emissive layer, an electron injection layer and a hole injection layer respectively formed at both sides of the emissive layer, and a total thickness of the electron injection layer and the second transparent electrode (in an inverted structure) or a total thickness of the hole injection layer and the second transparent electrode (in a conventional structure) is smaller than a length of one emission wavelength of the emissive layer. The evanescent wave generated by total internal reflection can penetrate into and be absorbed by the first phosphorescent/fluorescent layer to further emit light, thereby the overall external quantum efficiency of the LED chip is improved.

Abstract: Stent assemblies and related methods for creating an anastomosis employ a bioresorbable stent. A stent assembly includes a bioresorbable stent and one or more bioresorbable retention devices. The stent is configured for retaining a first section of a tubular organ in contact with a second section of the tubular organ to accommodate wound healing for connecting of the first and second sections of the tubular organ. A first end portion of the stent is configured to accommodate insertion into the first section of the tubular organ and inhibit removal from the first section of the tubular organ. A second end portion of the stent is configured to accommodate insertion into the second section of the tubular organ and inhibit removal from the second section of the tubular organ. The one or more retention devices are configurable to secure the first and second sections of the tubular organ to the stent.
