Abstract

SrTiO3(STO):Pr3+ nanopowders are synthesized because of their excellent photoluminescence (PL) performance. The PL intensity is enhanced by morphological control and oxygen vacancy. The “TEG-sol” method is used to prepare STO:Pr3+ nanopowders with a size lower than 10 nm. Abundant oxygen vacancies are formed in the nanopowders without any further processing. The effect of annealing temperature on the PL properties is systematically studied. Bright green-white emission is achieved from pristine STO:Pr3+. Red emission is obtained after annealing at a temperature higher than 400 °C. A flexible and translucent STO:Pr3+/polyvinylidene fluoride nanocomposite film is fabricated, which shows outstanding PL and dielectric properties.
