Besides the typical short-lived fluorescence with decay times in the nanosecond range. colloidal II/VI semiconductor nanoparticles dispersed in buffer also possess a long-lived fluorescence component with decay times in the microsecond range. Here. the signal intensity of the long-lived luminescence at microsecond range is shown to increase 1. https://www.diegojavierfares.com/amazing-price-Rubbermaid-8-Gallon-Plastic-Home-Office-Wastebasket-Trash-Can-with-Liner-Lock-p12316-big-deal/
