Paper Abstract

Under 405 nm diode laser excitation Europium doped Lanthanum fluoride glows bright white and revealed numerous wavelengths in the blue, green and red regions of the electromagnetic spectrum. These lines were emitted from 5DJ (J=0, 1, 2 and 3) to 7FJ (J=0, 1, 2, 3, 4, 5, and 6) levels. For the same excitation conditions Europium doped Calcium fluoride glows white with abundant blue emission and some yellow light. These materials appear to be promising candidates for solid state white light sources. Emission characteristics are described in detail.
