摘要

This paper proposes, for the first time, a quantitative description of the cross section of energy transfer between Nd3+ ions and quantum dots through rate equations model Nd3+ ions were embedded in a SNAB glass system with CdS quantum dots. This occurred because the Nd3+ ions absorbed photons emitted by CdS quantum dots with 457 nm excitation. Band overlap of the quantum dots luminescence band with the ion optical absorption bands caused photon absorption and produced valleys in the quantum dots luminescence spectrum. The energy transfer occurred via photon. The cross section of energy transfer was higher than that found in other semiconductor systems with rare earth.
