Abstract
We investigated terbium doped halide crystals. These materials were investigated by exposing them to blue and violet diode laser sources. Optical spectroscopy and lifetime measurements are performed for unambiguous assignment of spectral transitions and detect quenching phenomenon, if any. Terbium doped halide crystals revealed bright white light under low power diode laser excitation. Chromaticity diagrams are developed from spectral measurements. Color coordinates and color temperature are estimated. Our measurements indicate that terbium-doped fluorides are suitable for white-light generation under diode laser excitation.
