Fluorescent Nanocrystals 540nm - Hydroxy
The nanocrystals can be diluted into any buffered solution with a pH between 6.0-9.0 and an ionic strength of 160mM or less.
Outside of this pH range, and at higher salt concentrations, the nanocrystals may aggregate. If aggregation occurs due to too high or low pH, adjusting the pH back into the specified range with 1M NaOH or 1M HCl followed by sonication (approximately 10 seconds, three times, vortexing between sonications) redisperses the nanocrystals.
Features * Photostable (no bleaching) * Narrow and sharp emission peaks * All colors equally bright * Comparable quantum efficiencies (50%) throughout the visible spectrum * Semiconductor Grade * pH Neutral * The vial contain toluene dissolved CdxSe1-x/ZnS (core/shell) fluorescent nanocrystals coated with oleic acid as ligand.The nanocrystals should be stored in the dark at 4 oC . The shelf life is approximately one year under these conditions.
