Abstract The photostability of a colloidal single photon emitter in near-infrared regime at room temperature is investigated. The fluorescence lifetime, blinking phenomenon, and anti-bunching effect of a single CdTeSe/ZnS quantum dot with an emission wavelength of 800 nm at room temperature are studied. The second-order correlation function at zero delay time is much smaller than 0.1, which proves that the emission from single quantum dots at 800 nm is a highly pure single-photon source. The effects of the irradiation duration on the fluorescence from single quantum dots are analyzed. The experimental results can be explained by a recombination model including a multi-nonradiative recombination center model and a multi-charged model.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
