After the parameters analysis and comparison, we choose the suitable PMT and APD which is the best match with the crystalluminescence spectra as the photoelectric transducer.
通过分析比较各种光电转换器的参数，选取了与晶体发光光谱匹配最好的PMT和APD。

The efficient luminescence centres were found to be trivalent neodymium ions which, by a crystal field analysis, were shown to be located at zinc substitutional sites.
三价钕离子是有效的发光中心，利用晶场分析，三价钕离子主要是处在锌的替代位置。
