In this article, plasmonic waveguides aimed to controlling the colloidal quantum dot spontaneous emission rate have been designed. To this end, with considering aluminum and silver waveguides, the dependence of plasmonic emission rate to the dimension, material, and the place of quantum dots have been investigated. The results show that for a quantum dot with a distance of 5 nm from the edge of a silver waveguide with a gap of 20 nm and width of 30 nm, the plasmonic emission rate enhancement reaches 209 at the wavelength of 480 nm. This value for aluminum is 30. This waveguide is appropriate for ZnCdS/ZnS colloidal quantum dot with a photoluminescence peak at cyan wavelength.
