Abstract

When excited by the 6471-Å line from a krypton laser, blue and uv fluorescence has been observed in La

F_{3}

:

{Tm}^{3 +}

at room temperature. The main emission features have been identified as originating from the

{}^{1}D_{2}

and

{}^{1}G_{4}

levels, reached by a stepwise excitation process. A set of accurate Judd-Ofelt

Ω

parameters for La

F_{3}

:

{Tm}^{3 +}

has been derived from the measured lifetime of the

{}^{1}D_{2}

,

{}^{1}G_{4}

,

{}^{3}H_{4}

, and

{}^{3}F_{4}

levels.
