AgGaSe 2 , AgGa 0.9 In 0.1 Se 2 , and AgGa 0.8 In 0.2 Se 2 single crystals grown by the horizontal Bridgman technique were studied utilizing Raman spectroscopy excited with 633-and 784-nm lasers at temperatures varied from 77 to 300 K. The resonant Raman scattering associated with a transition from
Heavy metal Γuoride glass ZBLAN, with molar composition ZrF 4 (53)-BaF 2 (20)-LaF 3 (4)-AlF 3 (3)-NaF(20), was studied in vacuum at high temperatures up to 480 ΓC by Raman spectroscopy. The vitreous glass was found to crystallize at 330 ΓC, most probably to crystallites. High-temperature experiments
