The red -
emitting phosphor materials so far used are the principal factor responsible for this, because they have a particularly significant influence on the so - called color rendering index.
«With its unique luminescence properties the new material surpasses all red -
emitting phosphors yet employed in LEDs and has great potential for industrial applications» Schnick concludes.
For artificial lighting throughout the museum, conservators chose novel bulbs that use ultraviolet LEDs rather than the standard blue ones, and different blends of light -
emitting phosphors that better approximate natural light when operated at the low intensity needed to avoid damaging fragile pigments.
