Abstract
PURPOSE: To prepare the title composition having a higher luminescence than a red luminescent composition based on SnO2 under the excitation with low energy electron rays of an acceleration voltage of ≤1kV, esp. ≤100V, by mixing a composite oxide of Cd and Sn with a proper amount of a specific blue light-emitting flrorescent.
CONSTITUTION: A composition obtained by mixing (A) 1pt.wt. of a composite oxide of CdO.wSnO2 (0.1≤w≤10) and (B) 19W1/4 parts of a blue light-emitting fluorescent material such as (ZnS:Ag) (i.e. zinc sulfide fluorescent doped with silver), (ZnS:Ag, Al), [Zn(S, Se):Ag], [Zn(S, Se):Ag, Al], etc. The composition can be prepared at a lower cost than a blue luminescent composition based on In2O3, and nevertheless, emits more intense light by low energy electron rays of an acceleration voltage of ≥ about 80V.
