Work function control of functionally graded ZnO+Ga2O3 thin film for OLED applications

Spectrally narrow band-edge photoluminescence from AgInS2-based core/shell quantum dots for electroluminescence applications

“…40–44 While Ga 2 O 3 has been utilized in several applications for emitting devices, 45–48 photovoltaics, 49,50 and wavelength conversion for a white-light source, 51 its use in the ETL of OLEDs, as far as we know, is rather uncommon. 52 The expected CBM level is 3.32 eV, which is close to that of common ZnO (3.35 eV) and Zn 0.95 Mg 0.05 O (3.22 eV). 50,53 Consequently, the capability for electron injection into the QDs is comparable to that of the commonly used Zn-based oxides.…”

Transparent conducting Sn:ZnO films deposited from nanoparticles

“…Transparent conducting oxide (TCO) films show a high optical transmittance in the visible region as well as high electrical conductivity. This unique combination makes TCO films ideal for applications in many current and emerging optoelectronic devices, for example, gas sensors [1][2][3], touch-panel displays [4], liquid crystal displays (LCD) [5], organic light-emitting diodes (OLED) [6][7][8][9][10], smart windows [11] and solar cells [12][13][14]. TCOs such as Sn:In 2 O 3 (ITO) and Al:ZnO (AZO) are well established on an industrial scale.…”
