Zusammenfassung: | The utility model provides a scintillating crystals, crystal module, detector and positive electron transmission imaging device. Scintillating crystals include incident surface, side and with the playplain noodles of light sensor phase coupling, it has reflective coating to adhere to on the side, scintillating crystals is in the side position with the coupling has the transmission rete between the reflective coating, the transmission rete refracting index n2 with relation between scintillating crystals's the refracting index n1 does: N2 < n1, the transmission rete with be provided with surface microstructure between the reflective coating. The utility model discloses a scintillating crystals light -emitting rate is high, and the photon reachs light detector's the corresponding increase ofshare.
