主　　题：rare-earth trihalide crystal growth optical properties 

摘      要：In this paper, undoped LaCl3 crystal growth was reported by modified Bridgman *** starting materials used as charge for crystal growth was found to contain seven to three crystallized water molecules, and dehydration will take place when heating the raw materials at about 230 ℃ for several *** oxidization of LaCl3 during dehydration and growth can be avoided by adding a special scanvenger into the growing *** grown LaCl3 crystals are colorless and transparent, but very *** optical cut-off edge was confirmed to be 220 *** excited and X-ray induced emission spectra were measured at room temperature, whose peak is at 405 nm.
