In this work we have produced visible light emitting quantum dots (QD) of CdSe/ZnS and precipitated them onto the surface of porous silicon structure. Combining basic materials, such as porous silicon, with nanoparticles enables producing of low-cost ligh... see more

We report the enhancement of the optical second harmonic signal in non-centrosymmetric semiconductor CdS quantum dots, when they are placed in close contact with isolated silver nanoparticles. The intensity enhancement is about 1000. We also show that the... see more

These glutathione (GSH)-conjugated CdTe/CdSe core/shell quantum dot (QD) nanoparticles in aqueous solution were synthesized using a microwave-assisted approach. The prepared type II core/shell QD nanoparticles were characterized by UV–Vis absorption, phot... see more

AbstrakTelah dilakukan pencampuran nanopartikel emas dengan kuantum dot CdSe 618. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh penambahan nanopartikel emas terhadap intensitas emisi dan waktu peluruhan fotoluminesensi kuantum dot CdSe 618. ... see more

We have investigated in the framework of the envelope function approximation and taking into account the dependence of the electron effective mass on radius the energy of an electron inside a ZnTe/CdSe core/shell spherical quantum dot. In order to make th... see more

By using spin-coating technique, a low bandgap conjugated polymer, poly[2,6-(4,4-bis-(2-ethylhexyl)-4H-cyclopen-ta[2,1-b;3,4-b']dithiophene)-alt-4,7-(2,1,3-benzothiadiazole)] (PCPDTBT)  and its composite thin films have been prepared. The optical abs... see more

The fluorescence quantum yield or the efficiency of the fluorescence process is defined as the ratio of the number of photons emitted to the number of photons absorbed. In this report the experimental method to determinate photo luminescence (PL) quantum ... see more

In this paper, we present the systematically experimental results on the influences of pH of the reaction medium, molar ratio of the precursors on the synthesis in aqueous phase of CdTe quantum dots (QDs) and CdTe/CdS QDs with core/shell structure. Under ... see more

Quantum dot light emitting diodes (QD-LED) are considered to be the next advancement in display technologies. Quantum dot LEDs may improve the standard of LED technology by providing a purer color, cutting manufacturing cost, and having a higher efficienc... see more
