Epitaxial synthesis of uniform cerium phosphate one-dimensional nanocable heterostructures with improved luminescence.
Uniform CePO(4)@LaPO(4) and CePO(4):Tb(3+)@LaPO(4) one-dimensional single-crystalline nanocable heterostructures with highly enhanced photoluminescent emission have been synthesized via a mild and simple hydrothermal approach. The resulting one-dimensional single-crystalline nanocable heterostructures have smooth and uniform LaPO(4) sheaths, which is of great significance in effectively eliminating surface trap-states and suppressing the energy quenching in energy-transfer processes. The photoluminescence results for these one-dimensional nanocable heterostructures illustrate that the uniform LaPO(4) sheaths remarkably increase the luminescent efficiency.
