Effect of adjusting composition on the crystallization and luminescence properties in NaYF4:Er3+ embedded glass ceramics

Research on upconversion and temperature sensing properties of Er3+/Yb3+ codoped glass ceramics containing BaF2 crystals

“…In addition, the upconversion fluorescence spectra of the glass ceramics exhibits a Stark effect at 540 nm and 650 nm that is not presented in the precursor glass, which is due to the energy level splitting phenomenon caused by the crystal field around Er 3+ . 22 The calculated upconversion luminescence integral intensity of GC600 in the green spectral range (from 499 nm to 590 nm) is much higher than that of PG, which is favorable for optical thermometry. The fluorescence decay curves and average fluorescence lifetimes of PG and GC600 at 540 nm are given in Fig.…”

Lumino-structural properties of Dy3+ activated Na3Ba2LaNb10O30 phosphors with enhanced internal quantum yield for w-LEDs

“…15. The ve intense peaks correspond to 6 45,46 Hence, one can conclude that the synthesised phosphor shows potential for applications in near-Ultraviolet chips.…”

“…Phosphors are used, in the creation of several optoelectronic devices, including light converters, solid state lasers, solid state lighting, optical thermometer and optical ampliers, etc. [2][3][4][5][6][7] In the last decade, phosphor-converted white light emitting diodes (pc-wleds) have been studied signicantly owing to their key characteristic, such as efficient light output, low power consumption, longer operational lifetime (>100 000 hours), sturdiness and environmentally safer as compared to their predecessors, uorescent and incandescent lamp. [8][9][10][11][12] Nowadays, w-LEDs are widely used in plant cultivation (including vegetables, owers, herbs, etc.…”
