Definition of emissive in English:



  • Having the power to radiate something, especially light, heat, or radiation.

    ‘A more quantitative approach on absorption and emission of radiation in terms of absorptive power and emissive power are explained with specific references to block - body radiation.’
    • ‘A reflective and emissive roof system reduces both internal heat loads and the building's contribution to the ‘urban heat-island’ effect.’
    • ‘While the reflective and emissive properties of a roof are most important for its coolness, other factors such as insulation, roof orientation and roof pitch contribute to a building's overall thermal efficiency.’
    • ‘With only one emissive species the fluorescence anisotropy should not change over the emission band belonging to a particular electronic transition.’
    • ‘These television displays use a phosphor coating as the emissive medium, but do not rely on a single electron gun, as with CRT displays.’
    • ‘Since the PDP is emissive (produces its own light), the amount of light it emits can be flexibly regulated according to the use environment.’
    • ‘It should also be possible to use an emissive polymersome vesicle to transport therapeutics directly to a tumor, enabling us to actually see if chemotherapy is really going to its intended target.’
    • ‘This is rapidly improving, as wider gamut decoders are released, but these types of emissive displays will have trouble approaching the low-light detail of CRTs for some time to come.’
    • ‘A second prerequisite for observing fluorescence depolarization from a CT complex is that the complex is emissive.’
    • ‘The fact that biexponential fits are always required shows that different emissive species are present in the samples.’



/əˈmisiv/ /əˈmɪsɪv/


Mid 17th century (in the sense ‘that is emitted’): from Latin emiss- ‘emitted, sent out’ (from the verb emittere) + -ive.
