Sustainable biomass production is expected to be one of the major supporting pillars for
future energy supply, as well as for renewable material provision. Algal beds represent an …

A new Eu3+-activated oxyfluoride phosphor Ca12Al14O32F2: Eu3+ (CAOF: Eu3+) was
synthesized by a solid state reaction. Commonly red line emission was detected in the range …

A series of Mg2− xAl4Si5O18: xDy3+ (0≤ x≤ 0.18) samples were synthesized, for the first
time, by a solid state method both in a reducing atmosphere and in air. XRD, diffuse …

Quaternary alkaline earth zinc‐phosphate glasses in molar composition (40− x) ZnO–
35P2O5–20 RO–5TiO2–xE u2O3 (where x= 1 and R= Mg, Ca, Sr, and Ba) were prepared by …

Although a variety of Bi3+-activated common luminescent materials have been investigated,
few Bi3+-doped long afterglow phosphors have been discovered up to now. In this work, we …

Intense red photoluminescence has been observed in Eu 3+/Z+(Z+= Li+, Na+ & K+) co-
doped CaTiO 3 perovskite phosphor materials, synthesized through high temperature solid …

Mixed-valence Eu-doped CaZr (PO4) 2 was prepared in air atmosphere by a two-step solid-
state reaction for the first time. The reduction of Eu3+ to Eu2+ in air atmosphere was …
