To encounter thedrawbacks viz. lowsensitivity, high background hindrance, complicated procedure and high toxicity associated with traditionalfluo-rescent powders were resolved by using hollow/solid BaTiO3:Dy3+ (1-5 mol %) microspheres. The visu-alization of LFPs stained by the optimized BaTiO3:Dy3+ (2 mol %) hollow/solid microspheres exhibits well-defined ridgepatternswithhigh sensitivity, low backgroundhindrance, high efficiency and
