Removal of Narrow Spectral Lines from Experimental Photoluminescence Spectra of ZnS:Mn Nanocrystals

A smoothing method for noisy experimental photoluminescence spectra distorted by narrow spectral peaks and observed in ZnS:Mn bulk crystals and nanocrystals is proposed. Use of this method makes it possible to separate slowly varying components of the photoluminescence spectrum and narrow spectral p...

Zusammenfassung:A smoothing method for noisy experimental photoluminescence spectra distorted by narrow spectral peaks and observed in ZnS:Mn bulk crystals and nanocrystals is proposed. Use of this method makes it possible to separate slowly varying components of the photoluminescence spectrum and narrow spectral peaks caused by radiation of the He–Cd laser plasma or harmonics of N 2 -laser radiation that excite photoluminescence.
