    摘要: The invention provides a method for the formation of silicon nanoparticles, in sizes that fluoresce, by electrodeposition of silicon material onto a non-reactive (with HF) metal (e.g., platinum) surface from a solution of silicate and HF or HF/H2O2. In an embodiment of the invention, a positively biased substrate with a platinum surface is immersed in a solution of sodium metasilicate in HF/H2O2, a current is drawn and a coating of silicon nanoparticles is formed on the platinum surface.

    摘要: Multiple films of red-green-blue (RGB) luminescent silicon nanoparticles are integrated in a cascade configuration as a top coating in an ultraviolet/blue light emitting diode (LED) to convert it to a white LED. The configuration of RGB luminescent silicon nanoparticle films harnesses the short wavelength portion of the light emitted from the UV/blue LED while transmitting efficiently the longer wavelength portion. The configuration also reduces damaging heat and/or ultraviolet effects to both the device and to humans.
