Abstract
Pure yttrium oxide has three x‐ray‐excited emission bands in the blue‐u.v. region of the spectrum. Addition of thallium gives a broad emission peaking at about 580 nm with a decay time of less than 20 nanosec and Eu3+ emission in this matrix can be sensitized with thallium and bismuth absorption bands. On lowering the temperature from room to liquid N2 both and show new emissions as well as complex differences in the excitation spectra. The results in are discussed on the basis of bismuth occupying two centers in this matrix.Keywords
