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://fitnessgravesyardes.shop/product-category/left-rear-foot/
