Patent ID: 10984979

Abstract:
The disclosure provides a charged particle detector including a scintillator that emits light with stable intensity and obtains high light emission intensity regardless of an energy of an incident electron. The disclosure provides the charged particle detector including: a first light-emitting part (21) in which a layer containing Ga1-x-yAlxInyN (where 0≤x<1, 0≤y<1) and a layer containing GaN are alternately laminated; a second light-emitting part (23) in which the layer containing Ga1-x-yAlxInyN (where 0≤x<1, 0≤y<1) and the layer containing GaN are alternately laminated; and a non-light-emitting part (22) that is interposed between the first light-emitting part (21) and the second light-emitting part (23) (see FIG. 2).
