Quantitative description of the temporal behavior of the internal Mn 3 d 5 luminescence in ensembles of Zn 0.99 Mn 0.01 S quantum dots

摘要: We present an important step in resolving a long-standing controversy regarding the lifetime of internal ${\mathrm{Mn}}^{2+}$ $3{d}^{5}$ emission $\mathrm{ZnS}$ nanoparticles. Transients luminescence have been measured over more than five orders magnitude intensity, and time slot from $50\phantom{\rule{0.3em}{0ex}}\mathrm{ns}$ to $20\phantom{\rule{0.3em}{0ex}}\mathrm{ms}$. show that nonexponential decay behavior ensembles ${\mathrm{Zn}}_{0.99}{\mathrm{Mn}}_{0.01}\mathrm{S}$ quantum dots is result killer center statistics within dot ensemble, thus intrinsic effect Mn-doped II-VI
