Upconversion luminescence of Nd3+–Pr3+ codoped CsCl modified Ge–Ga–S glasses and the relevant energy transfer mechanism

Solvothermal synthesis and upconversion spectroscopy of monophase hexagonal NaYF4:Yb3+/Er3+ nanosized crystallines

“…Upconversion (UC) luminescent materials have numerous potential applications in solid-state lasers [1,2], solar cells [3,4], infrared photodetectors [5], three-dimensional displays [6][7][8] and biological labels [9][10][11]. Compared with organic dyes, quantum dots and metallic nanoparticles [12,13], UC inorganic fluorescent nano-materials possess many special advantages in the area of biological labeling, such as the absence of auto-fluorescence, reduced light scattering, greater luminescence penetration depths and high resistance of photobleaching.…”

Spectroscopic and magnetic behavior of Gd and Nd ions in lead–germanate glasses

“…Moreover, lead-germanate glasses can be easily obtained into fiber form and this enhances their status as materials of particular interest for telecommunications. [7,8] On the other hand, glasses and crystals containing rare earth (RE) ions have attracted great attention since the addition of these ions [7][8][9][10], as well as the addition of the transition metal ions [11][12][13][14][15], generate important properties for the host matrix. Such materials present extensive applications in fields such as information display and laser technology [7][8][9][10].…”
