Abstract

A highly transparent

{Eu}^{3 +}

-doped

{CaGdAlO}_{4}

(CGA) single crystal is grown by the floating zone method. The segregation coefficient, x ray diffraction, and x ray rocking curve are detected, and the results reveal that the single crystal is of high quality. The

f - f

transitions of

{Eu}^{3 +}

in the host lattice are discussed. The

{}^{5}{D_{0}} - {{}^{7}F}_{2}

emission transition at 621 nm (red light) is dominant over the

{}^{5}{D_{0}} - {{}^{7}F}_{1}

emission transitions at 591 and 599 nm (orange light), agreeing well with the random crystal environment of

{Eu}^{3 +}

ions in a CGA crystal. The decay time of

Eu : {}^{5}{D_{0}}

is measured to be 1.02 ms. All the results show that the Eu:CGA crystal has good optical characterization and promises to be an excellent red- fluorescence material.
