摘要
We investigate the emission properties of CuI film scintillators and the effect of distributed Bragg reflectors.The free-exciton emission and the donor-acceptor pair emission from the CuI thin film with the peak wavelengths of 410 nm and 420 nm are observed.However,for the two emission bands,the distributed Bragg reflector reflection results in different enhancements,which is interpreted by the varying transmittance with wavelength.Angle-dependence of emission profile is decided by the transmittance and DBR reflection,which may be useful in scintillation detection applications.
