We report unique applications of CdSe/CdS Dot-in-Rods in enhancing the photoluminescence of conducting natural Mimosa pudica (MP) fiber. The CdSe/CdS Dot-in-Rods were synthesized by hot injection technique. Upon characterization by transmission electron microscope, the composite CdSe/CdS is made of a CdSe spherical core of average diameter about 3.7 nm embedded in a Rod of CdS shell. We found the dimensions of CdSe/CdS Dot-in-Rods (rod length/rod diameter) to be of 56.7 × 5.7 nm and quantum yield being 75%. A layer of high-luminescence CdSe/CdS Dot-in-Rods was grown on surface of the touch sensing natural MP fiber by hydro-electro-chemical dipping method. The texture and topography characterizations have been carried out by using scanning electron microscopy techniques. We suggest a sensing plate which enhances photoluminescence potential of conducting natural fiber.
