OPTICAL PROPERTIES OF Ti3+ IN MgAl2O4 SPINEL
No full textAbsorption and lumienscence spectra of Ti3+ in synthetic MgAl2O4 are reported. It was found that luminescence spectra were dependent on excitation wavelength. An origin of Ti3+ luminescence is discussed
Positron Annihilation in and Compressibility of Water-Organic Solutions. The System Water-Pyridine
No full textThe results of positron lifetime and ultrasonic velocity measurements in dilute aqueous pyridine (PYR) solutions show unusual changes in ultrasonic, annihilation data in function of pyridine concentration. The results obtained suggest that strong structural changes occur in the system, in the region of low pyridine concentrations. Liquid clathrate hydrates forming in the system are supposed with unusual stoichiometry and untypical geometry. They are supposed to be very short-living and/or unstable
