Nd3+ dopant influence on the structural and spectroscopic properties of microcrystalline La2Mo2O9 molybdate

Correlation of crystal structure and optical properties of Ba0.97Nd0.0267Ti(1-x)WxO3 perovskite

“…In addition, it had been revealed that the emission intensity of RE ions-doped uorides and oxides can be modied with the addition of transition metals such as molybdenum (Mo) and tungsten (W). 10,11 Bokolia et al 12 pointed out that the UC emission intensity of Bi 4 Ti 3 O 12 : Er/Yb/W single crystal was signicantly enhanced with W doping by a distortion in the crystallographic symmetry. However, few reports on the effects of transition metals on the luminescence properties of RE ions -doped ferroelectric ceramics are found in the literature.…”

Люминесценция ионов Pr-=SUP=-3+-=/SUP=- и Nd-=SUP=-3+-=/SUP=- в двойных молибдатах

“…Множество исследований показывают перспективность применения молибдатов допированных редкоземельными ионами в качестве люминофоров, сцинтилляторов и лазерных сред [1][2][3]. Внимание к данным материалам обусловлено широкими возможностями варьирования их физико-химических свойств, термической и химической стабильности, а в некоторых случаях, крайне низким концентрационным тушением, несмотря на значительную концентрацию примеси [4].…”

Detection of oxide-ion and oxygen vacancy swapping via upconversion luminescence in La2Mo2O9:Yb3+,Er3+

“…groups,6,19,34 respectively. It can be apparently seen that P 4 and P 2 peaks show redshift to smaller wavenumber, again convincing the transformation trend from groups.…”

“…Thirdly, the near-infrared 976 nm laser excitable Yb 3+ -Er 3+ UC luminescence meets the in-situ non-contact requirement to monitor the working process of applied device or offers an alternative feasible approach to sieve or optimize oxide-ion conductors. Finally, the structural polymorphous phase of α-La 2 Mo 2 O 9 would be maintained with the dopant amounts of rare earth ions like Eu 3+ up to 20% 4,19. …”
