Tunable Emission

Rare-earth (RE) activated (Dy[Formula: see text]/Sm[Formula: see text] and Ce[Formula: see text]/Tb[Formula: see text]) polycrystalline CaSO4 phosphors were prepared by co-precipitation method. Powder XRD pattern confirmed their structure and phase, while FE-SEM investigation reflected the particle morphology. The optical absorption and emission analysis were carried out to find efficient energy transfer within codoped phosphors, a possible energy transfer mechanism was discussed and energy transfer efficiencies were calculated. The multicolor emission from these materials suggests sustainable and well-defined approach towards possibility of obtaining tunable emission for producing while light emission, which finds potential applications in field emission display (FED) and white light-emitting diodes (W-LEDs).

Tunable Emission

Organic-inorganic metal halides have become a multifunctional platform for manipulating photoluminescence due to high-efficient and tunable emissions, especially for lead-free Mn2+-based halides. Herein, the zero-dimensional (0D) bromides of (C5H14N3)2MnBr4 and...
