Light is generated in the electroluminescent layer containing an emissive (for example metal complex or polymer). Generally, in order to generate white-light emitting OLED (WOLED), the OLED organic stack has to contain red, green and blue emitters. Herein, we report WOLED where a platinum complex having di(2-pyridinyl)benzene-based tridentate ligand is the only emitter in the emitting layer. The Pt complex, which emits in the blue region, has a planar structure and thus has a tendency to form luminescent red-shifted aggregates. At the concentration of 20% in the emitting layer, the balanced contributions of monomeric and aggregate emissions of the Pt complex yield white light. The performance of WOLEDs devices of new architecture was studied. Luminance reaches 18000 cd/m2 and external electroluminescent efficiency is 7%. White light emitted by the devices is characterized by CIE (0.42, 0.38) and CRI = 65.","PeriodicalId":125701,"journal":{"name":"2014 Fotonica AEIT Italian Conference on Photonics Technologies","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116670006","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}

By modelling the impact of Rayleigh scattering on the concentrator performance, it is shown that the radius of the nanoparticles must not exceed 3nm, to limit optical loss and therefore optimize the effective optical concentration.","PeriodicalId":125701,"journal":{"name":"2014 Fotonica AEIT Italian Conference on Photonics Technologies","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123384918","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}

The analysis by interval-Principal Component Analysis (iPCA) has allowed us to outline the subtle differences in the Raman spectra induced by irradiation. In particular, this experimental approach has enabled to delineate radiation-induced changes in structure, protein, nucleic acid, lipid, and carbohydrate content. This has further confirmed that micro-Raman spectroscopy coupled to properly chosen data analysis methods is a very sensitive technique to detect molecular changes even in single human cells following exposure to ionising radiation. This would help developing innovative approaches to monitor radiation treatment effects so as to reduce the overall radiation dose and minimize damage to the surrounding healthy cells, both aspects being of great importance in the field of radiation therapy.","PeriodicalId":125701,"journal":{"name":"2014 Fotonica AEIT Italian Conference on Photonics Technologies","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126395186","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}

The knowledge of the temperature behaviour is important for assessing the feasibility of this sensor as a means for accurate and safety measurements of electric parameters in Medium Voltage (MV) equipment, in addition to the previously proved its suitability for the continuous monitoring of the phase of the voltage in MV electric boards. Results of thermal tests, carried out with the optical device inserted in a climate chamber, for simulating typical thermal excursion in MV equipment, evidenced a significant sensitivity reduction of the sensor response. Nevertheless it does not affect the phase sensitivity of the sensor, this measured temperature dependence limits an accurate measure of the voltage amplitude. A linear behaviour of the characteristic parameter of the ceramic material with temperature confirms the possibility of an active temperature compensation of the sensor response.","PeriodicalId":125701,"journal":{"name":"2014 Fotonica AEIT Italian Conference on Photonics Technologies","volume":"2009 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128062228","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}
