“…The ZnWO 4 was later seriously considered as a scintillator. [8,11] These literature data provide ample grounds for the supposition that inside the ZnO:W system there might exist other, more efficient phosphor compositions with blue or green emission. An additional lead was that, though classical phase analysis has established existence of only one tungstate phase ZnWO 4 in the ZnO± WO 3 quasi-binary system, [12] there are also indications of the existence of numerous other phases such as Zn 2 W 3 O 8 , [13] Zn 0.05±0.09 WO 3 , [14] Zn 0.2±0.3 WO 3 , [15] and others.…”

“…2), а длительность затухания изменяется в указанном ряду от 380 до 25 мкс при 300 К и коррелирует с величиной атомной массы катиона активатор (рис. Спектр люминесценции кристаллов ZnWO 4 при возбуждении как фотонами, так и электронами с энергией 250 кэВ состоит из монополосы на 2.6 эВ и совпадают с известными спектрами фото-, гамма-и катодолюминесценции ZnWO 4 в [73][74][75][76][77]. Нами установлено, что спектр свечения ZnWO 4 подобен по положению полосы свечения, по ее полуширине и кинетическим параметрам затухания характеристикам примесного свечения в кристаллах LiF-WO 3 (табл.…”

“…2). Но если в LiF-WO 3 cпектр свечения принадлежит кислородсодержащей примеси, заведомо вводимой в кристалл, то в натуральном фосфоре ZnWO 4 существование спектра свечения с такими же спектрально-кинетическими параметрами, как и LiF-WO 4 кристалле, вызывает ряд предположений [77,78]. простая перегонка -частичное испарение жидкой смеси путѐм непрерывного отвода и конденсации образовавшихся паров в холодильнике.…”

“…The origin of the G1 component seems to be unclear. As it has a low energy, Wang et al 60 in their study on ZnWO 4 interpreted the broad emission band close to 990 nm (with wavelengths ranging between 850 and 1100 nm) as being related to the presence of defect centers due to oxygen vacancies. In other terms, their broad NIR signal would be related to defect centers on the WO 6 6À groups.…”
