Scholarcy highlights

  • The photoluminescence from a variety of individual molecules1 and nanometre-sized crystallites2 is defined by large intensity fluctuations, known as ‘blinking’, whereby their photoluminescence turns ‘on’ and ‘off’ intermittently, even under continuous photoexcitation2
  • We report ternary core/shell CdZnSe/ZnSe semiconductor nanocrystals that individually exhibit continuous, non-blinking photoluminescence
