“…The electronic properties of rare earths (REs) are extraordinarily useful for diverse photonic technologies and devices, specifically in light-emitting diodes (LEDs), − photodetectors, waveguides for quantum signal processing and quantum memory, , lasers, , biolabels, and infrared radiation visualizers . Since RE-based materials show bright luminescence, they are widely used as imaging screens and/or scintillators which absorb X-ray radiation and convert it to photons of the visible range. − …”

Thin-film diamond−rare earth fluoride nanocomposites have been produced by chemical vapor deposition to be used as a source of intensive photo-and X-ray luminescence. The composites with embedded Eu-containing nanoparticles show highintensity orange narrow-band photoluminescence near the wavelength of 612 nm. Using β-NaGdF 4 :Eu instead of Eu(III) tri-(2,6pyridine dicarboxylic acid) and europium fluoride in the diamond matrix resulted in enhanced signal/noise ratio in the luminescence. The mapping of the spatial distribution of photoluminescence intensity on macro-and micro scale revealed highly uniform emission originated from the composite. The developed composite material with mechanically strong, highly thermally conducting and transparent diamond matrix opens a way to use the diamond− fluoride composites as photo-and X-ray luminescent screens (scintillators) capable to withstand high photon fluxes.
