The invention discloses a preparation method of
metal surface plasmon polariton-CdSe composite porous anodes. Specifically, gold nano particles of certain densities and certain sizes are deposited on the surface of conducting glass by the adoption of a three-
electrode system and the utilization of an electrochemical method, CdSe
quantum dots are deposited on the surfaces of the gold nano particles of the conducting glass through the utilization of the electrochemical method to obtain gold nano particle-CdSe
quantum dot composite anodes, and annealing treatment is carried out on the gold nano particle-CdSe
quantum dot composite anodes in an
inert atmosphere under the condition of 400-450 DEG C to obtain gold nano particle-CdSe
quantum dot composite porous anodes. The gold nano particle-CdSe
quantum dot composite porous anodes of multi-layer structures are constructed through the fact that the steps are repeated. According to the preparation method of the
metal surface plasmon polariton-CdSe composite porous anodes,
surface plasmon polariton enhancement effects of the gold nano particles are used,
absorption efficiency of incident light is effectively enhanced, photoelectric currents are improved, the multi-layer structures prolong a travel path of light, and light absorption is benefited. The preparation method of the
metal surface plasmon polariton-CdSe composite porous anodes is simple in operation of a preparation technology, easy to achieve, low in cost, and high in efficiency.
