  1. 1. Synthesis and development of compounds for nonlinear absorption of light

    Författare :Tomas Kindahl; Bertil Eliasson; Sascha Ott; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Platinum acetylide; nonlinear absorption; optical power limiting; oxazole; quantum chemistry calculation; quantum chemical calculation; triplet absorption; organisk kemi; Organic Chemistry; fysikalisk kemi; Physical Chemistry; Quantum Chemistry; kvantkemi;

    Sammanfattning : High-intensity light — for instance that from a laser — can be destructive, not only to the human eye, but also to equipment such as imaging sensors and optical communication devices. Therefore, effective protection against such light is desirable. LÄS MER

  3. 2. Nonlinear Absorbing platinum(II) Acetylides for Optical Power Limiting Applications

    Författare :Robert Westlund; Eva Malmström; Sergei Vinogradov; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optical power limiting; Polymer chemistry; Polymerkemi;

    Sammanfattning : During the past few decades, laser technology has had a strong impact on our society, providing important contributions to materials processing, data storage, communications, medicine, and defense applications. However, the progress in laser technology has also brought about the development of harmful portable high‐power lasers and tactical laser weapons. LÄS MER

  4. 3. Nonlinear materials for optical power limiting : characterization and modelling

    Författare :Hampus Lundén; Mikael Lindgren; Cesar Lopes; Bernd Eberle; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : High power laser pulses can be a threat to optical sensors, including the human eye. Traditionally this threat has been alleviated by colour filters that block radiation in chosen wavelength ranges. LÄS MER

  5. 4. Luminescence properties of flexible conjugated dyes

    Författare :Jonas Sjöqvist; Patrick Norman; Mikael Lindgren; Jacob Kongsted; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; force field; molecular dynamics; linear absorption; QM MM; absorption spectrum; emission spectrum; water solvation; stokes shift;

    Sammanfattning : In this licentiate thesis the luminescence properties of two flexible conjugated dyes have been studied. The first, Pt1, is a platinum(II) acetylide chromophore used in optical power limiting materials. LÄS MER

  7. 5. Bridge Mediated Electron Transfer in Conjugated and Cross-Conjugated Donor-Acceptor Compounds

    Författare :Erik Göransson; Leif Hammarström; Hans-Christian Becker; Michael R. Wasielewski; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electron transfer; Ultrafast; Long-range; Intervalence charge transfer; cross conjugation; hyperconjugation; Physical Chemistry; Fysikalisk kemi;

    Sammanfattning : Detailed understanding of electron transfer reactions is important in many aspects of chemistry, biology and solar energy conversion.The main aim of this thesis is to provide further insight into electron transfer through highly conjugated bridge structures. LÄS MER
