“…Rare‐earth (RE) ions, such as Er 3+ with abundant energy levels, can be excited by different light sources, which provides a flexible opportunity for achieving effective optical modulation by using appropriate pumping strategy. Furthermore, the optical property of Er 3+ ‐doped materials is very stable without any fluorescence blinking and bleaching, showing great potential for optical modulation application 17–19 . NaYF 4 has low phonon energy, and Er‐doped NaYF 4 nanocrystals are recognized as the most efficient up‐conversion (UC) luminescent materials 20,21 .…”

Efficient optical modulation enables a significant improvement of optical conversion efficiency and regulation of optical response rate, showing great potential for optoelectronics applications. However, the weak interaction between photons poses a strong obstacle for manipulating photon–photon interactivity. Here, upon simultaneous excitation of 850 and 1550 nm, a fast–slow optical modulation of green up‐conversion (UC) luminescence in oxyfluoride glass ceramics containing NaYF4:Er3+ nanocrystals can be achieved. Compared with the sum of luminescence intensity excited by the two single‐wavelengths, green UC luminescence excited by simultaneous two‐wavelength presents an obvious increase by approximate six times. Interestingly, the response rate of green UC luminescence relies on the pump strategy of two‐wavelength excitation, showing as high as two times of the fast–slow response difference. The fast–slow optical modulation of green UC luminescence under two‐wavelength excitation is promising for emerging applications in all‐optical switching.

“…Since the discovery of rare Earth elements by John Gadolin in 1794, this element has been widely used in lighting, [1][2][3] laser, [4][5][6] communication, [7][8][9] biological imaging [10][11][12][13] and other fields. According to the change of photon frequency, the luminescence of rare Earth ions can be divided into down-conversion luminescence and up-conversion luminescence.…”

The phase analysis, luminous intensity, and luminescence lifetime of different doping concentrations of Tb3+ (1 mol % - 11 mol %), Yb3+ (9 mol % - 54 mol %), Er3+ (0.1 mol % - 1.1 mol %) ions and different introduction concentrations of Y3+ (1 mol % - 6 mol %) and Lu3+ (0.5 mol % - 3 mol %) of Gd2O2S series phosphors were studied systematically. In addition, the energy transfer model of Tb3+-Yb3+-Er3+ was established by analyzing the changes of luminous intensity and luminescence lifetime of novel (Gd, Y, Lu)2O2S phosphors co-doped Tb3+, Yb3+ and Er3+ which were prepared by the coprecipitation-high temperature solid-state reaction method., The luminescence intensity ratio equations of the sample excited by 980 nm was obtained at 313-553 K. And the absolute sensitivities were 0.0033 (313 K). This work is of reference value to the study of the mechanism of up-conversion system.
