Abstract

The impact of irradiation with higher and lower quantum energy than that corresponding to the fundamental absorption band of CdSe nanoplatelets has been studied. We show that the irradiation wavelength and oxygen strongly influence the photoluminescence of nanoplatelets. We demonstrate also that irradiation of CdSe nanoplatelets dry layers leads to a reversible change in their photoluminescence quantum yield.

CdSe量子纳米血小板发光的光活化

摘要

研究了比CdSe纳米片的基本吸收带高和低的量子能辐照的影响。我们表明辐照波长和氧气强烈影响纳米片的光致发光。我们还证明了CdSe纳米片干燥层的辐照导致其光致发光量子产率的可逆变化。
