A scholar used "荧光粉, 稀土, 发光性能, X射线" as search terms. Do you think the search engine would return the abstract "采用凝胶-燃烧法制备了Li2BaSiO4∶Eu3+红色荧光粉.用X射线衍射分析(XRD)表征了Li2BaSiO4∶Eu3+荧光粉的结构,重点考察了激活剂Eu3+的浓度对Li2BaSiO4∶Eu3+发光强度的影响.结果表明,Li2BaSiO4∶Eu3+荧光粉为六方晶系结构.以394nm的近紫外光激发样品,Li2Ba1-xSiO4∶xEu3+荧光粉发红光,其中以614.4nm发射峰发光最强.在800℃灼烧3h条件下,当Eu3+的浓度为5.5％时,Li2BaSiO4∶EC+荧光粉的发光性能最佳.Eu3+的掺杂对Li2BaSiO4∶Eu3+荧光粉的发射光谱的峰形和峰位无明显影响."? Answer yes or no.
