FIELD: optics.
SUBSTANCE: blue-emitting phosphor is a silicate of rare-earth elements in nano-amorphous state, having composition Ca2Gd8(1-x)Eu8xSi6O26, where 0.001≤x≤0.5, characterised by blue radiation with maximum at 455 nm, half-width 77 nm, intensity 14000-14263 relative units and narrow line of red radiation with maximum at 615 nm with intensity of 400-416 relative units.
EFFECT: invention can be used for imaging of light in ultraviolet range in systems of white light-emitting diodes (WLED) and optical displays.
