Abstract: C1.00137 : LaF3:Ce/CdTe nanocomposites for radiation detection application
Author:
Radiation detection demands new scintillators with high quantum
efficiency,
high energy resolution, and short luminescence lifetimes.
Nanocomposites
consisting of quantum dots and Ce$^{3+}$ doped nanophosphors may
be able to
meet these requirements. Here, we report the luminescence
enhancement of
LaF$_{3}$:Ce/CdTe nanocomposites which were synthesized by a wet
chemistry
method. The results show that CdTe luminescence in LaF$_{3}$:Ce/CdTe
nanocomposites is enhanced about five times. Energy transfer, light
reabsorption, and defect passivation are the likely reasons for the
luminescence enhancement
