The main purpose of this paper is to derive the analytic valuation formulae of xed range accrual notes (FiRAN) and oating range accrual notes (FlRAN) in the context of an a¢ ne term-structure model incorporating stochastic long-run mean, stochastic volatility and jumps according to the empirical ndings of An- dersen et al.(2004). We propose a quasi-analytic pricing and hedging solutions for range accrual notes and these solutions are demonstrated in sensitivity analysis. Our numerical results show all these three factors signi cantly a¤ect the values and hedging strategies of range accural notes, and the factor of stochastic mean plays the most important role in either valuation or hedging.

The Eu3+-doped CdTe quantum dots (QDs) have been successfully synthesized in aqueous phase through microwave-assisted hydrothermal method. The as-prepared products were characterized by X-ray diffraction (XRD) technique, high-resolution transmission electron microscope (HRTEM), energy dispersive spectrum (EDS), X-ray photoclectron spectrum (XPS), UV-visble (UV-Vis) absorption spectrum and photoluminescence (PL). As the results show, the average sizes of the cubic phase CdTe and CdTe:1%Eu3+ are an average size of 3.7 nm and 3.5 nm, respectively. The average lattice parameter of CdTe:Eu3+ decreases with increasing Eu3+ ions concentration. Furthermore, compared to green emission of the host CdTe, the CdTe:1%Eu3+ presents additional orange fluorescence emission of Eu3+ ions. Recombination luminescence color is almost located in the yellow region of the CIE 1931, and the CIE 1931 coordinate is (0.448, 0.513). The effect of different Eu3+ doping concentration on the luminescence of CdTe:Eu3+ QDs was discussed in detail. It suggests that CdTe:Eu3+ QDs are potential phosphors for white light-emitting materials.
