Nano-synthesis and characterization of Er ³⁺ , Ho ³⁺ and Li ⁺ co-doped, Er ³⁺ and Li ⁺ co-doped and Ho ³⁺ and Li ⁺ co-doped lanthanum borosilicate luminescent materials (LaB

In the present investigation, lanthanum borosilicate nanomaterials doped with Er 3+ /Ho 3+ and co-doped with Li + or both Er 3+ and Ho 3+ co-doped with Li + are synthesized using a sol–gel pyrolysis method, taking urea as an organic precursor.
