Abstract

本发明公开了一种发光产品，具体地说是适用于有选择性地诱集害虫应用光源的一种铕激发磷酸锶近紫外荧光粉。本发明所采用的技术方案是该荧光粉的化学组成为：M2P2O7:Eu；M为碱土金属；其制备原料为：磷酸氢锶、磷酸氢二氨、三氧化二铕；其制备方法用固相合成法，按摩尔比1∶0.02∶0.05准确称量原料，研细混匀后将混合原料放入高温炉，充入氢氮还原气在300℃-1200℃中烧结1-8小时，冷却后，取出研磨后即得紫外荧光粉，适用于汞线253.7nm激发。本发明的近紫外荧光粉中的阳离子主要为碱土金属、稀土金属，烧结工艺相对简单，相比降低了成本。

一种铕激发磷酸锶近紫外荧光粉
技术领域：本发明涉及一种发光产品，具体地说是适用于有选择性地诱集害虫应用光源的一种铕激发磷酸锶近紫外荧光粉。
背景技术：随着科技发展和社会进步，人们已普遍开始意识到农药对人类健康、食品安全性、环境的负面影响。从“飞蛾扑火”的自然现象人们受到启发，光可以引诱飞蛾，至此开辟了人类历史上防治害虫手段的新篇章，灯光诱杀害虫的作用已越来越为人们所重视。最初人们使用煤油灯、篝火，进而用黑光灯、高压汞灯等方式诱杀害虫，这些方式在防治过程中都暴露了致命的缺点，即效果差，诱杀无选择性，大量杀伤天敌，破坏生态平衡，消耗资源大，人畜安全无保证等问题。
发明内容：本发明的目的在于克服了现在利用灯光诱杀害虫存在的弊端，针对灯光的波长、波段对人身及目标生物的各种影响，靶标生物对电子辐射波、频率的不同反应，利用昆虫的复眼结构和对特定光波的趋性差异，提供了有选择性地诱集害虫的应用光源的一种铕激发磷酸锶近紫外荧光粉。
本发明所采用的技术方案是该荧光粉的化学组成成分由以下化学式表示：
M2P2O7:Eu；
M为碱土金属；其制备原料为：磷酸氢锶、磷酸氢二氨、三氧化二铕；其制备方法用固相合成法，按摩尔比1∶0.02∶0.05准确称量原料，研细混匀后将混合原料放入高温炉，充入氢氮还原气在300℃-1200℃中烧结1-8小时，冷却后，取出研磨后即得紫外荧光粉。
本发明的有益效果是由于该荧光粉适用于汞线253.7nm激发。本发明的近紫外荧光粉中的阳离子主要为碱土金属、稀土金属，烧结工艺相对简单，相比降低了成本。
本发明的紫外荧光粉采用干混法，也可采用燃烧法等其它方法，也可达到相似的效果。
具体实施方式：实施例1：该荧光粉的化学组成成分由以下化学式表示：
M2P2O7:Eu；

实施例2：其制备原料为：SrHPO4、(NH4)2HPO4、Eu2O3；它们之间的摩尔比相应为1∶0.01∶0.05；其制备方法为按摩尔比将SrHPO4、(NH4)2HPO4、Eu2O3准确称量原料，研细混匀后将混合原料在300℃-1200℃还原气中烧结1-8小时，冷却后，取出研磨后即得紫外荧光粉。
实施例3：其制备原料为：SrHPO4、(NH4)2HPO4、Eu2O3。它们之间的摩尔比相应为1∶0.01∶0.03；其制备方法为按摩尔比将SrHPO4、(NH4)2HPO4、Eu2O3准确称量原料，研细混匀后将混合原料在300℃-1200℃还原气中烧结1-8小时，冷却后，取出研磨后即得紫外荧光粉。
实施例4：其制备原料为：SrHPO4、(NH4)2HPO4、Eu2O3；它们之间的摩尔比相应为1∶0.01∶0.02；其制备方法为按摩尔比将SrHPO4、(NH4)2HPO4、Eu2O3准确称量原料，研细混匀后将混合原料在300℃-1200℃还原气中烧结1-8小时，冷却后，取出研磨后即得紫外荧光粉。
实施例5：其制备原料为：SrHPO4、(NH4)2HPO4、Eu2O3；它们之间的摩尔比相应为1∶0.02∶0.02；其制备方法为按摩尔比将SrHPO4、(NH4)2HPO4、Eu2O3准确称量原料，研细混匀后将混合原料在300℃-1200℃还原气中烧结1-8小时，冷却后，取出研磨后即得紫外荧光粉。
