摘要
近红外光写入的光激励发光材料不仅能推进光激励发光材料在信息存储领域的实用化进程,也能在生物成像和编码方面发挥独到的作用.然而,近红外光写入型的高容量光激励发光材料仍旧十分缺乏.首先以具有热辅助紫外光激发增值填充容量的BaSi2O5∶Eu2+,Nd3+材料作为基础,进一步掺杂Yb3+离子实现近红外光的热转化,然后复合含有蓝、紫光发射的NaYF4∶Yb3+,Tm3+上转换发光材料,成功展示了980 nm激光调控的强度复用光存储.本研究不仅提供了一种高效的近红外光写入型的光激励信息存储材料,还表明了基于热辅助光激励发光材料构建高效近红外光写入的高简效性.
Abstract
Photostimulated luminescent(PSL)materials written by near-infrared(NIR)light can not only promote the practical application of PSL materials for information storage,but also play a significant role in biological imaging and coding.However,high-capacity PSL materials for NIR writing are still lacking considerably.Herein,BaSi2O5∶Eu2+,Nd3+ with thermal-assisted increment filling capacity that could be excited by ultraviolet light was first selected,and Yb3+ ions were further doped to it for optimizing the thermal conversion of NIR light.Combined with the up-conversion luminescent material NaYF4∶Yb3+,Tm3+ containing blue and violet light emission,intensity multiplexing of optical storage application was successfully demonstrated solely using a 980 nm laser regulation.This study provides an efficient NIR light writing-type PSL material and demonstrates the high efficiency for NIR writing on thermal-assisted photoexcited luminescent materials.
