Preparation and luminescent properties of CaCO₃:Eu³⁺ hollow sphere by co-precipitation method

Classification of thermoluminescence features of CaCO3 with long short‐term memory model

“…[6] Bacterial calcium carbonate precipitation or cementation plays an important role in various application areas of civil engineering, such as repairing cracks in rock and concrete, improving bearing capacity, reducing permeability, and increasing the tensile hardness in sand with dilative tendencies. [5] The luminescence properties of CaCO 3 have been investigated by some researchers [2,7,8] but, according to the best knowledge of authors, no computational model has been applied to this using the results obtained with a thermoluminescence (TL) method. [9][10][11][12] Therefore deep learning of the long short-term memory (LSTM) [13][14][15] model was used to classify the TL data.…”
