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.
