The nano- particle of germanium and the germanium alloy and method in order to produce those

摘要

At the time of this inventing, crystal germanium or electrochemistry etching of the germanium alloy creates the color cluster where the nano- particle is well separated. Another strong band appears in the photo luminescence spectrum under the 350nm excitation which possesses the lowest peak at the wave length which is identified in 430nm, 480nm, 580nm and 680 1100nm. As for this material, it being possible to manufacture in the colloid, diameter of the separate set which it can re-construct to the film and crystal etc it is possible to make disperse in the luminous characteristic nano- particle 1 - 3nm, Selective figure Figure 1
