다양한 질량비의 SiO2, Hollow SiO2 나노 파티클들을 Poly(methylmethacrylate) (PMMA) 용액에 분산하여 OLED 내부 광추출용 산란층을 제작 하였다. 구형의 실리카 나노 파티클들은 약 300 nm의 평균 입자 사이즈를 나타내었다. 실리카 나노 파티클 고분자 분산액은 스핀코팅을 통하여 기판위에 코팅 되어 제작되었다. 내부가 비어 있지 앉은 SiO2 나노 파티클 산란층의 경우 높은 산란 특성을 나타내었으며 (30wt%, 588 nm, Haze 0.37) Hollow SiO2 나 노 파티클의 경우 상대적으로 낮은 산란 특성을 나타내는 것을 확인할 수 있었다 (30 wt%, 588 nm, Haze 0.16). 하 지만 Hollow SiO2 나노 입자의 경우 매우 낮은 back-scattering으로 인한 높은 투과 특성을 나타내었다 (30 wt%, 588 nm, 85%). 또한 입자의 함량 증가에 따른 투과도의 감소와 산란의 증가 비가 상대적으로 매우 높음을 확인할 수 있었다.

This study shows that the vertical migration speed of sound scattering layers (SSLs), which is distributed in near Funka Bay, were measured by 3D velocity components acquired from a bottom moorng ADCP. While the bottom mooring type has a problem to measure the velocity vectors of sound scattering layer distributed near to surface, both the continuous vertical migration patterns and variability of backscatterers were routinely investigated as well. In addition, the velocity vectors were compared with the vertical migration velocity estimated from echograms of Mean Volume Backscattering Strength, and estimated to produce observational bias due to SSLs which is composed of backscatterers such as euphausiids, nekton, and fishes have swimming ability.

The effect of light scattering layers (400 nm, TiO particle) of 4 m thickness on the dye-sensitized solar cell has been investigated with a 12 m thickness of photo-anode (20 nm, TiO particle). Two different structures of scattering layers (separated and back) were applied to investigate the light transmitting behaviors and solar cell properties. The light transmittance and cell efficiency significantly improved with inserting scattering layers. The back scattering layer structure had more effective transmitting behavior, but separated scattering layer (center: 2 m, back: 2 m) structure (9.83% of efficiency) showing higher efficiency (0.6%), short circuit current density (0.26 mA/cm) and fill factor (0.02). The inserting separating two scattering layers improved the light harvesting, and relatively thin back scattering layer (2 m of thickness) minimized interruption of ion diffusion in liquid electrolyte.
