crystals. Luminescence measurements were carried out on backscattering experimental setup with two sources Nd:YAG and argon lasers. On the basis on previously performed absorption spectra, the emission spectra were obtain and then the luminescence lifetimes. It was found that crystals doped by praseodymium exhibit remarkable luminescence properties.
