<title>Initital research of three-dimensional volumetric display based on di-frequency upconversion</title>

Abstract

Three-dimensional display may be one of the most wonderful techniques attracting scientists to research on. But most of current approaches are fictitious ones. On the CLEO'94 , E. A. Downing and L. Hesselink et al. reported a virtual three-dimensional volumetric display using Pr doped fluoride glass upconversion luminescence which is evaluated as a new excellent physics achievement in 1996.The ZBLAN:Pr glass is proved by L. Hesselink to be a interesting material for three-dimensional volumetric display based on upconversion. In the processes of upconverting near-infrared radiation to visible, the 1G4 level of Pr locates at an important position. But the transition probability of 3H4-1G4 proved to be one or two order of magnitude smaller than other strong transitions. So to improve the population on 1G4 has an practical significance.In this paper, we report a simple 3-D volumetric display experiment which has used the upconversion sensitization *This project is supported by the National Natural Science Foundation of China 122 SPIE Vol. 3560 • 0277-786X198/$1O.00 Downloaded From: http://proceedings.spiedigitallibrary.org/ on 06/26/2016 Terms of Use: http://spiedigitallibrary.org/ss/TermsOfUse.aspx

The study of two-color excitation upconversion of Pr(0.5)Yb(3):ZBLAN

“…The upconversion research on Pr-doped material is an interesting topic [1][2][3][4][5][6][7]10,[16][17][18][19] , which has excellent applications in laser [17,18] , volumetric three-dimensional display [10][11][12][13][14][15][16] , and so on. The excited state absorption plays a key role in step-by-step absorption upconversion, avalanche upconversion, and part of sensitization upconversion among all rare earth ion doped materials and all applications.…”

“…totally up to now [1 -19] , in which Pr 3+ doped material is an interesting research field [1][2][3][4][5][6][7]10,[16][17][18][19] . Multi-photon upconversion volumetric 3-d display was proposed first in 1994 [15] and published in Science in 1996 [10] based on the di-frequency upconversion effect of Pr:ZBLAN glass material.…”

“…It has very useful applications, owing to its advantages of self-spatial vision and total-solidification, high reliability and speedy operation. Thus, it is important to know the upconversion property, especially the excited state absorption in Pr:ZBLAN material [7][8][9][10][11][12][13][14][15][16] . And moreover, the upconversion research has been done using a lot of materials, just like glass, crystal, vitroceramics and so on.…”

“…And moreover, the upconversion research has been done using a lot of materials, just like glass, crystal, vitroceramics and so on. Many spectroscopic studies are carried out on ZBLAN fluoride glass system because it has excellent luminescent property and can be manufactured into fiber or large bulk material and benefit laser operation or volumetric three-dimensional display [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] . In conclusion, it is significant to investigate the excited-state absorption upconversion property of the Pr 3+ ion doped ZBLAN material under two-color excitation [7] .…”

Enhanced two-step two-frequency upconversion luminescence in a core/shell/shell nanostructure

“…For example, Hou, Chen and Sun et al studied and optimized the TSTF UCL performances of RE-doped fluoride glasses and analyzed their application prospects in volumetric 3-D displays. 31–33…”
