Covalent tethering of a Ru(II) dye to gallium nitride surfaces has been accomplished as a key step in the development of innovative sensing devices in which the indicator support (semiconductor) plays the role of both support and excitation source. Luminescence emission decays and time-resolved emission spectra confirm the presence of the dye on the semiconductor surfaces, while X-ray photoelectron spectroscopy proves its covalent bonding. The O(2) sensitivity of the new device is comparable to those of other ruthenium-based sensor systems. This achievement paves the way to a new generation of integrable ultracompact microsensors that combine semiconductor emitter-probe assemblies.
将钌（II）染料共价键合到氮化镓表面已经完成，这是开发创新感应设备的关键步骤，其中指示剂支撑（半导体）同时起到支撑和激发源的作用。发光发射衰减和时间分辨发射光谱证实了染料存在于半导体表面，而 X 射线光电子能谱证明了其共价键合。新器件的 O(2)灵敏度可与其他基于钌的传感器系统相媲美。这一成就为新一代集成式超紧凑型微传感器铺平了道路，这些传感器结合了半导体发射器-探针组件。
