Scintillation Detector Ce:YAG crystal

Product Overview

Description

Product Description                                                                                                  

1. A well-established scintillator and has many attractive properties

2. Fast decay (60~70ns), high light yield, emission peaks at 520-550nm that well matched with the sensitivity of

    commercial Si-CCD detectors

3. Good mechanical and chemical stability. 

4. A very appropriate crystal for imaging screens, LED lighting and laser lighting.

Features                                                                                                                      

1. Virtually no afterglow emissions

2. Emission peaking at 550nm is well matched with CCD detectors

3. Reasonably fast with a decay time of 70ns

4. YAG (Ce)'s light yield increases linearly with the total energy of the electron beam,

    whereas the response of phosphors dramatically decreases.
