Abstract
A method to improve light extraction from scintillators in a gamma ray detector, the method including forming a roughened layer on a light-emitting surface of the scintillators, the roughened thin layer having a pillar/column or a corn-shaped structure.
Claims13
A method to improve light extraction from scintillators in a gamma ray detector, the method comprising:
- forming a roughened layer on a light-emitting surface of the scintillators, wherein the forming step comprises:
- depositing a first thin layer on the light-emitting surface of the scintillators, the first thin layer including a thin film or scattered particles;
- and
- depositing a second thin layer on the first thin layer, the second thin layer having a roughened surface.
