摘要:
A storage and reconstruction apparatus for radiation image is comprised of a radiation image storage medium (3) made of phosphor glass powder (5) in which activators are formed according to a radiation image. The radiation image storage medium (3) emits a fluorescent light (25) by irradiation of an excitation light (22), and the emitted fluorescent light (25) is detected and converted into an electrical signal. The electrical signal is treated by an image processor (28) and the radiation image is reconstructed.
摘要:
Lumineszenter Leuchtstoff auf der Basis von mit Mangan dotiertem Zinksilikat mit einem Teil des Siliziums substituiert durch lonenpaare aus den Gruppen IIIA und VA des periodischen Systems so, daß die Willemitstruktur erhalten bleibt. Der Leuchtstoff enthält Zn 2-y MN y Si 1-2x (Z) 2 xO 4 wobei Z aus der Gruppe AlP, GaAs, BP, GaP, BAs und AlAs gewählt ist und y ≦0,25 und x ≦0,5 ist.
摘要:
Disclosed are highly luminescent nanostructures, particularly highly luminescent quantum dots, comprising a nanocrystal core of InP and shell layers of GaP and AlP. The nanostructures may have an additional shell layer. Also provided are methods of preparing the nanostructures, films comprising the nanostructure and devices comprising the nanostructures.
