Luminescence properties of Sm3+ doped glass ceramics containing Ba3Gd(PO4)3 crystal phase

With the continuous development of science and technology, glass ceramics containing phosphate crystal phases have the advantages of good network formation, low propagation loss, easy preparation, good optical stability, low phonon energy and high solubility of rare earth ions, while being well suited as light emitting materials for various optical devices. Sm3+ ions are commonly used as activating ions for orange-red light and are a suitable source for lighting and display devices. In this work, Sm3+ doped glass ceramics containing Ba3Gd(PO4)3 crystal phase have been prepared through melt crystallization method. Compared with the precursor glass sample, glass ceramics had higher luminescence intensity. Sm3+ doped glass ceramics containing Ba3Gd(PO4)3 crystal phase had been a promising orange-red luminescent material with potential application in w-LEDs.
