Again, the question arises why do we see different degree of photoluminescence enhancements from the same particle as we vary the excitation wavelength Unlike the previous experiments with variety of organic fluorc hores shown in Figure 4.10, here we only use one kind of fluorc hore CdSe quantum dots... 

Figure 19.8 Photoluminescence enhancement of rhodamine monolayers covalently attached to glass with various amounts of nanotextured silver on top. (A) Extinction spectra of substrates with no silver (a) and increasing amounts of silver from (b) to (e). (B) Resulting photoluminescence from these subtrates for excitation at 450 nm.

Figure 4 The reaction between ninhydrin and an amino acid, leading to the production of a dark purple compound known as Ruhemann s purple. Further treatment with a metal salt (zinc(ll), cadmium(ll), or mercury(ll)) results in the formation of a luminescent coordination complex.
