Figure Lengend Snippet: Absorption and photoluminescence spectra and TEM images of ( a , b ) CdSe/ZnS synthesized for 10, 30 and 90 min and ( c , d ) CdSe/Cd 1−x Zn x S NPLs synthesized for 5, 10 and 20 min.
Article Snippet: To evaluate the relative photoluminescence quantum yield (PLQY), fluorescein dissolved in ethanol (PLQY = 0.91) was employed as a reference standard .The absorbance of the sample and the reference was measured using a UV-visible spectrophotometer (X-ma 3000, Human Corporation), and the photoluminescence (PL) spectra were collected using an optical spectrometer (OCEAN SR6, Ocean Insight) under excitation with a 455 nm LED light source (M455F3, Thorlabs).
Techniques: Synthesized
