Fig. 5.19 (a) Linking CdSe quantum dots to Ti02 particle with bifunctional surface modifier (b) light harvesting assembly composed of T102 film functionahzed with CdSe Q-dots on optically transparent electrode (OTE). [Adapted (in gray scale) from [348]]... [Pg.291]

Figure 16.16 Room temperature absorption cross-section per Q-dot for CdSe Q-dots dispersed in hexane. From right to left, spectra ate shown for Q-dots with radii of 3.39, 2.40, 1.87, 1.54, and 1.18 nm. In the inset, the integrated oscillator strength per particle for the lowest-energy transition (lSelS3/2 h) is plotted vs. the particle radius. (Reproduced with permission from C. A.

Quantum dots are semiconductors composed of atoms from groups II-VI or III-V elements of the periodic table, for example, CdSe, CdTe, and InP (39). Their brightness is attributed to the quantization of energy levels due to confinement of an eleetron in a three-dimensional box. The optical properties of quantum dots can be manipulated by synthesizing a (usually stabilizing) shell. Such Q-dots are known as core-shell quantum dots, for example, CdSe-ZnS, InP-ZnS, and InP-CdSe. In this section, we will discuss the different properties of quantum dots based on their size and composition. [Pg.563]

Figure 16.17 shows the remarkable agreement between theory and experimental findings for CdSe quantum dots. The experimental error of approximately 5 lel. percent results from the inhomogeneous radial size dispersion of the Q-dots. The complex refractive index for bulk CdSe at 350 run is /wi = 2.772 0.7726r. The absorption... [Pg.566]
