Enhancement of upconversion luminescence in Tm3+/Er3+/Yb3+-codoped glass ceramic containing LiYF4 nanocrystals

Intense Upconverted White Light Emission from Tm3+ - Er3+ - Yb3+ Doped Zinc Tungsten Tellurite Glasses

“…This can be achieved by controlling the type and the amount of REIs. Hence there is a requirement for novel phosphor materials doped with different type and amount of REIs [1][2][3][4][5][6][7].…”

Up-conversion luminescence of Er3+/Yb3+ co-doped LiYF4 nanocrystals in sol–gel derived oxyfluoride glass-ceramics

“…Recently RE-doped LiYF 4 nanocrystals have received considerable attention in particular for the up-conversion (UC) properties and related applications, leading to an increased interest for the nanochemistry of this compound. Hence, various preparation methods for the synthesis of colloidal dispersion of nanocrystals [11][12][13][14][15] or nanocrystals embedded in silica glass matrix (so called oxyfluoride glass-ceramic) [16][17][18][19] have been proposed and their up-conversion properties have been reported [11,15,19]. On the other hand, these properties, in particular the UC mechanism, are greatly affected by the nanosize effects and by the environment through the quenching effect of media (in the colloidal dispersion) ( [15] and references therein [20]).…”

Frequency-conversion properties of Eu3+ doped chlorophosphate glass ceramics containing CaCl2 nanocrystals

“…Glass ceramics containing rare earth ions have been one of the most interesting fields of research during the past decade, due to their potential application in optical devices such as photon upconversion materials and solid-state lasers [1][2][3][4][5][6][7]. Transparent glass ceramics are composite materials containing nanocrystallites with sizes less than 30 nm embedded in a glassy matrix [8][9][10].…”
