Deep, high contrast microscopic cell imaging using three-photon luminescence of β-(NaYF(4):Er(3+)/NaYF(4)) nanoprobe excited by 1480-nm CW laser of only 1.5-mW

It is challenging to achieve deep microscopic imaging for the strong scattering in biotissue. An efficient three-photon luminescence can effectively increase the penetration depth. Here we report that β-NaYF(4): Er(3+)/NaYF(4) UCNPs were excited by a 1480-nm CW-laser and emitted 543/653-nm light thr...
