| Abstract: | The luminescence spectra and radiation induced color centers of undoped and various doped lead tungstate crystals were studied. The radiation induced color centers in all samples (excluding the undoped and Sb doped samples) may be decomposed into two kinds of color centers peaked at 400 and 500um, respectively. For undoped samples, the peaks of radiation induced color centers are at 360 and 530um, and those of Sb doped samples are at 350 and 430um. These two kinds of color centers are located at two sides of the luminescence spectra and with different damage and recovery constants. |
