Nanoparticles editing sample

Before

The light-emitting 5,6,11,12-tetraphenylnaphydrotermalhacene (rubrene) nanoparticles (NPs) prepared by the reprecipitation method were treated with a hydrothermal process. The diameters of hydrothermally treated rubrene NPs were changed from 100 nm to 2 μm depending on hydrothermal temperature. We observed that the photoluminescence (PL) characteristics of rubrene NPs varied with the hydrothermal temperature. The luminescence color of the pristine rubrene NPs was yellow-orange, and it was changed to blue as the hydrothermal temperature increased at 180 °C. The light-emitting color distribution of the NPs was confirmed through the confocal laser spectrum microscope. The variation of PL of the hydrothermally treated rubrene NPs originated from the different size distribution of the NPs.

After

Light-emitting 5,6,11,12-tetraphenylnaphthacene (rubrene) nanoparticles (NPs) prepared by reprecipitation were treated hydrothermally. Hydrothermally treated rubrene NP diameters changed from 100 nm to 2 μm, depending on hydrothermal temperature. Photoluminescence (PL) characteristics of rubrene NPs varied with hydrothermal temperatures. Luminescence of pristine rubrene NPs was yellow-orange, changing to blue as the hydrothermal temperature increased to 180 °C. The light-emitting color distribution of the NPs was confirmed using confocal laser scanning microscopy. Variations in PL of hydrothermally treated rubrene NPs resulted from different size distributions of the NPs.
