Abstract :
This work reports on the thermal diffusivity of the SiO2–Na2CO3–B2O3–Al2O3 (SNAB) glass system doped with semiconductor nanocrystals of CdS and Nd3+ ions. Thermal diffusivity (D) was obtained by the Thermal Lens technique. It is shown that D decreases up to 30% when SNAB is doped with CdS nanocrystals. The effect is discussed in terms of heat transport by phonons as well as interface and surface scattering.
