<p>The invention provides a nuclear battery comprising nanoparticles of a radioactive isotope mixed with an electroluminescent phosphor layer (42), and a photovoltaic cell (46) arranged to receive photons from the electroluminescent phosphor layer. Typically the isotope is an a orβemitter, such as Ni-63 or Am-241. This allows sealed long-life batteries to be produced.</p> |
