Here, the C/L-band light emission (1.53 μm-1.63 μm) of InAs/In0.25Ga0.75As quantum dots (QDs) epitaxially grown on Ge substrate by solid-source molecular beam epitaxy (MBE) is reported. By hybrid III- V/IV epitaxial growth, ultra-thin and anti-phase domains (APD) free III-V materials are achieved on Ge substrate. Step-graded InGaAs metamorphic buffer layers are applied to reduce the strain in InAs QDs in order to extend the emission wavelength. At last, a high quality InAs/In0.25Ga0.75As QD structure on Ge(001) substrate is obtained, which has a strong C/L-band emission centered at the wavelength of 1.6 μm with a full-width- half-maximum (FWHM) of 57 meV at room temperature.","PeriodicalId":285199,"journal":{"name":"2017 Asia Communications and Photonics Conference (ACP)","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133580871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Charge-transfer (CT) state is beneficial to harvest triplet exciton utilization in fluorescent organic light-emitting diodes (FOLEDs) by efficient reverse intersystem crossing. However, the CT-dominated emissive state seriously decreases PL efficiency in such materials. Our strategy is to combine both locally-excited (LE) state and CT state into hybridized local and charge-transfer (HLCT) state, aiming at a balance between high PL efficiency and high exciton utilization. As a solution, a quasi-equivalent hybridization is obtained in TBPMCN, and its nondoped OLED exhibited a very high performance: a pure blue emission with a CIE (0.156, 0.159), a high EQE of 7.8% and a high exciton utilization of 97% without delayed component. Furthermore, the excited state properties were systematically investigated in donor-acceptor (D-A) system using time-dependent density functional theory (TDDFT). The hybridization and de-hybridization processes between LE and CT states were involved with an increasing distance between donor and acceptor. What is more, HLCT state composition can be finely modulated by D-A strength, linkage, etc. Using HLCT conception, we achieved high-efficiency blue, green, red and even NIR luminescent materials and their FOLED devices. In a word, the excited state modulation could be a practical method in designing low-cost, high-efficiency FOLED materials.","PeriodicalId":285199,"journal":{"name":"2017 Asia Communications and Photonics Conference (ACP)","volume":"10 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134356039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
