| 제목 | Characteristics of Dy2O3 doped glass system for laser sealing applications |
| 초록 | Laser sealing in local areas of photonic devices is a key technology in order to achieve the high level of functionalization, miniaturization and durability. However, transparent sealing glass materials with have high absorption efficiency on the infrared wavelength of lasers diode, has not been fully developed for transparent photonic device. Therefore, we developed new Dy2O3 doped glass systems, which were prepared by general melting and quenching method. They were evaluated for the optical, thermal, and thermo-mechanical properties. It was observed that Dy2O3 doped glass systems showed above 77.5% of transparence. Absorption peaks around 800nm due to 6H15/2 6F5/2 energy transition of Dy3+ became deeper with increase of Dy2O3. The glass transition temperature(Tg) showed in the range of 386 ~ 389 (℃) and coefficient of thermal expansion(CTE) were in the range of 9.0 ~ 9.3 (x 10-6/℃). It means that the concentration of Dy2O3 cannot mainly affect the thermal and thermomechanical properties. In addition, the local sealed spots were still transparent after being sealed between two solar cell panels using a 808 nm laser diode. Considering those results obtained above, Dy2O3 doped glass systems developed in this work shows the potential candidate for sealing transparent phonic devices. |
