Quantum dots (QDs) have potential applications in optoelectronics, biosensing, biolabeling, memory devices, and sources of laser light. We show that alloyed CdSeTe QDs possess a nonlinear change in their photoluminescence spectra, correlated to size and composition, as monitored by the versatile bench-top FluoroMax® spectrofluorometer. QDs’ emission can be as long as 850 nm, which may aid imaging deeper into living tissue than visible light can penetrate.
