Abstract

CdTe quantum dots have intense photoluminescence but exhibit almost no x-ray luminescence. However, intense x-ray luminescence from CdTe quantum dots is observed in LaF 3:Ce/CdTe nanocomposites. This enhancement in the x-ray luminescence of CdTe quantum dots is attributed to the energy transfer from LaF 3:Ce to CdTe quantum dots in the nanocomposites. The combination of LaF 3:Ce nanoparticles and CdTe quantum dots makes LaF 3:Ce/CdTe nanocomposites promising scintillators for radiation detection.
