Hideo Hosono 교수의 연구실은 비투과성 및 고효율 광전자 소재 개발에 초점을 맞추고 있습니다. 특히 납을 포함하지 않는 하이드로겔 및 구리 기반 할라이드 퍼보스카이트와 같은 저차원 전자 구조를 가진 비독성 반도체 소재를 연구하여, 높은 발광 양자수율을 실현하고자 합니다. 또한 실리카-게르마나이드 유리 내 산소 공석과 같은 광흡수 메커니즘을 규명함으로써 고에너지 광학 특성의 기초를 다지고 있습니다.

Halide perovskites, including CsPbX<sub>3</sub> (X = Cl, Br, I), have gained much attention in the field of optoelectronics. However, the toxicity of Pb and the low photoluminescence quantum yield (PLQY) of these perovskites hamper their use. In this work, new halide materials that meet the requirements of: (i) nontoxicity, (ii) high PLQY, and (iii) ease of fabrication of thin films via the solution process are explored. In particular, copper(I) halide compounds with low-dimensional electronic s
The sources of an absorption band at \ensuremath{\sim}5 eV observed in ${\mathrm{SiO}}_{2}$:${\mathrm{GeO}}_{2}$ and ${\mathrm{GeO}}_{2}$ glasses have not been unambiguously identified. Results reported here are consistent with the source of two types of neutral oxygen vacancies. Samples of ${95\mathrm{S}\mathrm{i}\mathrm{O}}_{2}$:${5\mathrm{G}\mathrm{e}\mathrm{O}}_{2}$ and ${90\mathrm{S}\mathrm{i}\mathrm{O}}_{2}$:${10\mathrm{G}\mathrm{e}\mathrm{O}}_{2}$ were prepared by a chemical vapor deposit
