%X The blue OLED emission from a mobile phone was characterised, revealing a sharp emission band centred at ¦Ė = 445 nm with a 3dB bandwidth ¦¤¦Ė ~ 20 nm. It was used to excite Rhodamine 123 doped within a ”°giant”± mesostructured silica sphere during fabrication through evaporative self-assembly of silica nanoparticles. Fluorescence was able to be detected using a standard optical microscope fitted with a green transmission pass filter and cooled CCD and with 1 ms exposure time demonstrating the potential of mobile platforms as the basis for portable diagnostics in the field.
