Abstract

Efficiencies of ∼1%, 0.1%, and 0.01% have been achieved, respectively, in the red, green, and blue with simple infrared‐to‐visible conversion sources. Saturation effects observed in the blue‐emitting phosphor Y_0.65Yb_0.35Tm_0.001F₃ have been explained. The first and second cross‐transfer coefficients for this Yb, Tm system have been determined to be 1.3×10⁻¹⁷ and 8.3×10⁻¹⁵ cm³ sec⁻¹.
