Abstract

Crystals with quantitiative additions of adding quantitatively VEB or iso-VEB to TBP were prepared, and the time response of the absorption and flurescence spectra were examined for their thin firks evaported at room temperature, 100[ddot]C, 130[ddot]C and also 140[ddot]C.

The crystallization rate was found to depend no the purity of the specimen and also on the substrate temperature. Furthermore, we confirm that the purity of TBP estimated in our previous paper¹ is reasonable, and that the crystallization rate can be used as a new monitor of purity.
