Fig. 6. Connection between the oscillator strength, fluorescence lifetime and NPL area.

Fig. 6

a Plot showing the (red diamonds) measured room-temperature oscillator strength FStark and (blue circles) calculated FAbs for different samples of 4.5 ML nanoplatelets with different surface areas. The horizontal red line represents the average oscillator strength <FStark>, while the blue line displays a best fit of FAbs to a straight line through the origin. Here, S is the nanoplatelet surface area in nm2. b Comparision of (red diamonds) room temperature radiative lifetime τStark calculated from FStark and (green circles) the average luminescent lifetime τPL determined from luminescence decay measurements. The red and green line represent the sample average, whereas the error bars indicated the 95% confidence interval on both the averages
