According to the many shortcomings in PDP, and with the theory of quantum cutting and the study of VUV, the paper offers a new idea to prepare high-efficient PDP luminescent material.
针对目前PD P荧光粉存在的不足之处，从量子剪裁理论与真空紫外光谱出发，对高效PD P荧光粉的研究提出了新思路。
Most of the quantum cutting systems hitherto is fluoride, which have no practical value due to their low stability, low absorbability and low energy conversion efficiency under VUV exciting.
科学家们已经证实的量子剪裁体系多为氟化物，由于它们在VUV下的不稳定性和氟化物的活性，以及氟化物基质在VUV波段的弱吸收、能量转换效率低，所以没有实际应用价值。
Especially, an effective three-photon and four-photon infrared quantum cutting of Er0.3Gd0.7VO4 crystalline excited by visible and near-violet light are found for the first time in the present paper.
更重要的是，我们首次发现了Er0.3 Gd 0.7 VO4晶体材料的可见激发的三光子的有效的红外量子剪裁现象和浅紫外激发的四光子的有效的红外量子剪裁现象。
