Near infrared molybdenum oxide quantum dots with high photoluminescence and photothermal performance

Abstract

The synthesized near infrared molybdenum oxide quantum dots perform excellent red fluorescence imaging performance and photothermal performance, which have 600, 650 and 700 nm three unique peaks excited at 540 nm, with a high quantum yield around 20%. Meanwhile, with 808 nm NIR laser excitation, 10 mg/mL modified Molybdenum oxide quantum dots can increase temperature up to 72.2 °C within 150 s and 77.7 °C within 270 s, respectively.
